On a lowly night in Royal Woods, Lincoln is trying his best to focus on studying for his science recitation for the next day. He has his textbooks and other resource materials scattered on his room. He takes the information he obtains and places them on assorted color cards. But he has trouble understanding the periodic table of elements.

Though he tries his best to memorizing the elements and their corresponding chemical symbols, Lincoln suddenly gets disturbed from the commotion outside of his room. He opens the door to see his sisters making all sorts of ruckus along the halls, in usual Loud House fashion. Combustion bursts from Lisa's room, making her get covered in soot as she walks out of her room. Lola drives her kiddie cart around the halls, and is being chased by Lynn who dodges every commotion in parkour style. Luna and Lana play with lightsabers and proceed to go on full duel. Lucy tests her organ skills to Luna's synthesizer and improvises playing Danny Elfman's score of Batman. Luan is rehearing to Lily with sock puppets. And Lori and Leni shriek over Leni's texting with a boy she likes. All contribute to a whole lot of loudness in the Loud House.

Naturally, Lincoln finds this very frustrating on his need to focus studying. He shares his sentiments to the readers of this chapter, "Well, what can I say? I live in a house of ten sisters. Noise will always go by default. But why does it have to be this time?!" As the noise intensifies, Lincoln slams the door close and returns to his bed, setting a digital notebook on his lap. "Necessarily, I'd go to the least distracting areas of the house. But I don't want to end up in another setup that my sisters had in store, in case I ignore them completely. Might as well distract myself for a little while."

Lincoln then places the notebook on his lap and browses to his Twitter homepage. Out of response about the noise on his house, Lincoln posts: "Another Loud house noise session. Need moment to study. Anybody knows how?" He then follows up with a disclaimer: "And I ain't going back to my ear 'buds'. Anything else."

After that, he goes on random browsing on the Internet as he patiently waits for the noise to die down. Unfortunately, it just intensifies when he overhears Lori sharing Leni's messages to her sisters, which, of course, make them screech in excitement.

While going along with the motions, Lincoln suddenly receives a direct message from an anonymous user in Twitter. The message says, "Open your window." Curious, Lincoln opens his small circular window and goes back to his laptop to wait for what is about to happen. As he types to confirm of opening the window, an arrow with a heavy-duty rope tied suddenly hits to the corner of his room. He checks it out, only to see a girl ziplining to his direction. As she comes close to his way, Lincoln recognizes her.

"Wait, Lena? Is that you?" Lincoln utters. It is Lincoln's neighbor (and newfound twin) Lena Lark, who shot an arrow to his room and dashes now to his side.

"Make way Lincoln! Twinnie's coming!" Lena yells as she speeds up towards Lincoln's window. But before passing through the very small circular window, Lena ends up stuck there. She tries to pull herself out, to no avail. "Uhmm Lincoln, a little help."

"Oh coming!" Lincoln then stacks pillows to help Lena get pulled out of the extremely small window.

"Why you have such a small window?" Lena asks.

"Don't blame me. There's not enough room in this room," Lincoln says, "This was not supposed to be a room."

"I can see that."

"So what brings you here?"

"Well, saw your message. So I came to the rescue."

'Wait, that was you who messaged me?"

"Yeah, you didn't know?"

"I never sense you following me."

"You didn't? I even replied on your tweets."

"Probably haven't noticed the confirmation." He says this forcefully as he is forcefully trying his best to pull Lena to his room.

"Yeah, we'll take that later. But for now, better pull me out first. My butt's sticking out of your window. Don't wanna end up like Winnie the Pooh." She then grasps on Lincoln's white hair locks to help herself out.

After a number of pulls, and with all his force, Lincoln tugs Lena out of the window, but they both fall onto the bed, making Lena land closer to Lincoln's face. And just at a close (and intimate) gaze at each other, they immediately repel from each other.

That becomes a true awkward moment for the both of them. They take the time cooling themselves down, after such an expected encounter. Granted, the two have been really close to each other. But every time they end up so close to each other, literally and figuratively, butterflies suddenly roll in their stomach. Lincoln tries to brush off the blush from his face, but Lena lets her face redden. He notices his friend on her messy hair, her lop-sided ponytail, her murky green jacket, white top, red skirt, black leggings and white Chuck Taylor shoes, Lena's usual get up.

Feeling her shyness, Lincoln takes initiative to start where they drop off. "So…what's up?"

"Uhmmm…I just thought…we…or I…could help," Lena nervously implies. "You know?"

"Yeah…that would be good," Lincoln quickly replies.

"Yeah, I'll get my stuff," Lena says. She then heads back to the window and howls to her house, signaling Loui to hook up Lena's backpack to the rope and have it slide to Lincoln's room. "Thanks Loui!" she shouts to her sister, who gives Lena thumbs up. Lena then scatters the contents inside her bag to the bed. "Okay, where you say you were having a hard time on?"

"Well uhhh pretty much chemistry," Lincoln informs her, "We have this big recitation tomorrow on reciting some parts of the periodic table."

Lena is digging on her stuff and happens to retrieve an item that can help Lincoln in studying. "Hmmm…I seemed to have the perfect solution for that."

The item happens to be a periodic table of elements flash cards that Lena somehow mixes it up with Lacy's belongings or forgets to depose from her bag after using it for school. She then uses the said cards as part of Lincoln's studying. The cards show the chemical symbol at the front, while providing the detailed information of their chemical properties, like atom number, electronic configuration, boiling and freezing points and others. She flashes a card with an "Ag" on it.

Lincoln then answers, "Ag? Isn't that silver?"

"Good. Very good," Lena confirms. She then flashes another card that shows "Sn". "How about this?"

"Tin?"

"Atomic number?"

Lincoln then counts with his fingers and relies on his stock knowledge in determining tin's atomic number. "Well, it's a metal. So, it might land on 48?"

"Nope. Go on."

"49?"

"Keep going."

"50?"

"Good! Very good Lincoln. You're getting your chemistry correctly. Really mind-blowing." She then flashes a card with "K". "This one?"

"Oh, that's potassium. Present in bananas."

"That is good! Great job Linc!" Lena then proceeds to hug Lincoln in celebration for this wonderful feat.

"Nahh, it's all about appreciating chemistry, even though I think it's rancid in paper, but cool for real."

"Come on Lincoln. You make chemistry good."

"No, we make good chemistry."

But after hearing Lincoln's accidental statement, Lena gasps in surprise. Hearing those words just grumbles her stomach further and reddens her face more.

Lincoln realizes what he said and tries to explain it to Lena. "Oh, I'm sorry what I said. Never meant that…"

"No, it's okay. I…am…uhmmm…"

"Well, got carried away from there, huh?"

"Yeah…really much."

"But seriously, we make a good team I have to say. Honest, Lena."

"Yeah, we really do make a good team, twinnie."

"Yeah…" They try to shrug off the feeling of uneasiness that wraps around their bodies. They never realize that they are into each other's feeling, seeing that their relationship has been platonic. "Why don't we just continue with the others?" Lincoln insists.

"Sounds good," Lena replies, making her sigh in relief from their uneasy awkwardness.

Lena then takes the time to help (or even force) Lincoln to study for his recitations. His study sessions mostly involve Lena guiding him through visual aids, challenging him not to get slapped after every time he causes a mistake and browsing through supplementary material. Lena even implements both a reward system and a reinforcement module to help him concentrate. Eventually, after those came to pass (the reinforcement module eventually made him upset) Lincoln deems himself confident on his studying.

"Well, here goes nothing. If tomorrow ends up a failure, I'm not sure what else would," Lincoln utters.

"You can make it," Lena encourages him, "You just have to focus."

But ironically, the noise from the Loud sisters intensify after they giggle over Leni's conversation. And their subsequent shrieks rock the room.

"Ironically enough," Lincoln reacts.

"Well, what can work for you? Please tell me," Lena insists.

Lincoln then answers at the top of his head, "Well, if something exciting happens. Something I might expect and end up happy. And there's that something I didn't expect but I end up being happy. I don't know. It's something I could be inspired of, that I would be distracted away from my noisy sisters."

With that, Lena thinks of a solution out of Lincoln's wishes. She approaches Lincoln closer and asks, "Like this?" And just like that, she kisses Lincoln by the lips. Lena takes advantage on giving him something that would both distract and excite him to concentrate on studying. As she pulls out her kiss, Lincoln is stunned at this unexpected gesture from his next door neighbor that he dubs as his twin sister. "So, effective?" Lena then receives a text message from Loui, who informs her of dinner already set in the Lark house. "Gotta get back Lincoln. I shall see you tomorrow." She then pulls out the arrow she shot earlier, takes her stuff and ties the rope to the window pane. "You know what, after school, let's meet. If that became effective, I'd take the shot on treating you anywhere you like, okay?" Just like that, she uses the rope to climb down the house (with easy passage out of the small, circular window) and hurries back to her house.

Lincoln is just there, stunned at what Lena did. Nevertheless, feeling smitten by an 11-year-old hipster girl, his face reddens to full capacity. Lincoln cannot help but fall in love.
