AN: I think it's a shame there's a lack of quality Quintessential Quintuplet fanfics. So, I'll just do it myself. So, this series will be one-shots. I'll do a fic for each girl writing cute events between Fuutarou's hypothetical confession and the inevitable wedding.

Chapter 1: Itsuki Confession

"What?" Itsuki couldn't believe what she was hearing. Why her? Why now?

"Ever since graduation...no before that...ever since our final year started I've been thinking about romance." Fuutarou explained as he nervously gripped a lock of his hair. "And…I love you."

"But what about…." Itsuki wanted to argue but she also didn't. She looked to her sisters for guidance. Four nigh-identical girls each with a gambit of emotions on their face. Ichika hid behind a fake smile. Nino was more exasperated. Miku's face was unreadable. And Yotsuba was looking at the floor and starting to ease herself out of the room.

"I love all of you." Fuutarou said. "I want to be a part of your family, and I don't want to come between you and your sisters."

"I..I can't lie." Itsuki said. "My heart is fluttering." Fluttering was doing it a disservice. She felt like her heart was going to fly out her throat. "But why me and not them. Surely, one of them has put in more effort."

"I don't know." Fuutarou said. "You put in the right effort." He stepped forward. "Rena." At that note Yotsuba bolted out the door.

"Yotsuba!" Itsuki shouted as she chased after her. Nino stopped her and Ichika went to chase after Yotsuba herself. She looked back at Fuutarou. His face didn't have an ounce of confusion on it. In its place was frustrated acceptance.

"I should have talked to her before." Fuutarou said.

"I can't." Itsuki said. "As much as I want to be selfish for once I can't under these circumstances." Her hands were shaking. "Because I'm…."

"Rena, but you're not the one I met back then." Fuutarou guessed. "I suspected as much. You are Quintuplets afterall."

"You knew?" Itsuki said as she faced Fuutarou. "You knew!"

"Itsuki, my feelings are my own. You and Yotsuba both taught me that the past isn't as important as the future we can make."

"I guess." Itsuki sighed as she looked to the door. Yotsuba had done so much to suppress her feelings. But no amount of suppression can change your heart. This day was inevitable. Their feelings had reached Fuutarou's heart. They all loved him, but there could only be one winner. All they could do was keep their head up and be happy for whoever Fuutarou picks. "I'm not going to reject you. But we need time to think."

"I understand. This is a big deal." Fuutarou said, making Itsuki's heart throb in excitement. That right there was why she loved him. He could be stubborn, self-centered and arrogant. But he really cared about people. He cared about her and all her sisters. And over the years, Itsuki had fallen in love with that side of him as well as his serious side. But did he know all this time? Probably. Why else would he ask her out so suddenly?

"Don't think for too long though." Nino finally spoke up. "You have a bad habit of overthinking things."

It was true. It's one of the reasons she struggled on tests. It was also why she had kissed Fuutarou back at the bell before their final year started. Wait, did he know about that too? Did he know that that was her testing her own feelings by acting impulsively for once?

He couldn't at least wait for the two of them to be alone? Guess it was too much to ask for given how the other girls had been behaving all year. And it's probably for the best that they let the other girls know right away. It was just tactless and insensitive to not wait for a definite answer before letting the others know. As happy as Itsuki was, guilt over Yotsuba's role in all this had infected her. She, and possibly Ichika, were the only ones who knew about back then.

"Anyway, Fuu-Kun, shouldn't you get going?" Nino said.

"I'm fine with him staying as long as he wants." Miku said.

"Any other day, I'd agree." Nino stepped in front of Fuutarou and crossed her arms. "We have things to talk about, and when Ichika brings Yotsuba back, you being here might make things worse."

"Um…" Fuutarou started but Nino began pushing him out.

"Come on, give us some alone time. I'm sure Raiha will have dinner ready by the time you get home." She pushed him out of the apartment and shut the door on him. "You." She shot daggers over at Itsuki sending a shiver down her spine. "You have some nerve."

"I didn't tell him to confess like this!" Itsuki defended, putting her hands up as Nino stormed over right next to her.

"Nino." Miku raised her hand to interrupt.

"I never suspected you'd be the deadliest rival yet. Damn it! Why you."

"I don't know." Itsuki said. "But..."

"You lied to me." Nino huffed as she turned her back on Nino.

"Don't be upset." Miku said. "You promised…"

"I know." Nino sighed. "But it doesn't make it less infuriating. How was I supposed to prepare for that?"

"I suspected." Miku said.

"Well aren't you smart!" Nino said. "What I don't get is Yotsuba. What was that about?"

"It's a long story. Do you remember that trip to Kyoto a few years ago?" Itsuki asked.

"Yeah." Nino said and then a moment later she remembered. "I…" Nino had suspected that the blonde boy in that Fuutarou was actually him. And she knew she had recognized him. He was the one Yotsuba had met back then. "Then Yotsuba...all this time ...why didn't she say anything?"

"Guilt." Miku understood very well. Guilt is what motivated much of Yotsuba's life.

"It's just something she's going to have to grow out of." Itsuki said. "Fuutarou already knew and he chose me anyway, which means that there was no lingering feelings for Yotsuba from back then."

"And you knew?" Nino asked.

"Fuutarou told me about his experience. I suspected Yotsuba and she confirmed it. Then when you and I ran off, we plotted to get him to move on. And we basically dumped him."

"Wait." A sign of recognition crossed her face. "That was you!" Amazing how one confession could make so many odd events click together and make sense. It must have been fate. A series of decisions all leading to this moment. If that wasn't destiny, then there was no such thing.

"So what are going to do now?" Miku asked.

"I'm going to go on a date with Uesugi-Kun. I'm going to see if I'm really in love with him and he's really in love with me." Itsuki was already formulating a plan. This was not something she could take lightly. Her future, Fuutarou's future and the future of her family was on the line. There were two things all the Nakano sisters could agree on, they all loved Fuutarou and they'd do whatever it took to keep each other together. One way or another, Fuutarou was family, and making sure these feelings were genuine was the only way to keep it that way.

AN: First time I'm writing these characters and It's probably the biggest challenge. A future with Itsuki and Fuutarou is honestly a long shot. But I love her, so I'm starting on her side of things first.
