Hiro was feeling strange lately. He would have some headaches once in a while or he would find himself thinking about… stuff. Not to mention that he had caught once or twice himself looking at some random girl. Also, he noticed that his voice was starting to change as well. And as awkward as it was, he was growing some hair in certain parts of his body. He also was experimenting mood swings, which was kind of annoying. And Tadashi seemed to notice his strange behavior, because he just grabbed Hiro's shoulders and sat him on his chair. While Tadashi sat on Hiro's bed and sighed.

Hiro looked at his brother. Tadashi said he was going to explain him what was happening to him (which was a relief) but every time Tadashi opened his mouth to say something, he will close it again and look away, eyeing every single object in the room except Hiro. Now THAT was annoying and Hiro was starting to lose his patience. He crossed his arms and tapped his foot in frustration. He frowned. "Well?" He asked.

Tadashi finally looked at him. "It's just, it's hard to explain…" He looked at his baby brother with sadness. "You are dying."

"What!?" Hiro almost jumped out of his chair when Tadashi laughed. Hiro frowned and slapped his brother on the arm. Tadashi took a moment to breath.

"You should have seen the look on your face." Tadashi chuckled.

Hiro rolled his eyes. "Very funny. Now spit it out. What's going on with me?"

Tadashi's smile fell. "Well…" He looked away. "It is kind of awkward to explain." He rubbed his face. "If only dad was here…" He mumbled into his hands. He looked back at Hiro. "Well… it's…um… What you are going through happens to every boy, it happened to me when I was your age."

Hiro just looked at him.

Tadashi continued. "Your body starts to change into that of a bigger boy. It's called puberty."

Hiro blinked.

"It happens to everyone. Even to girls, but their puberty is different." Tadashi said. "You start to grow taller or muscular, depending on the guy. Or hairier. And your body changes constantly."

Hiro blinked twice.

Tadashi wanted to slap himself. "Are getting what I have told you so far?"

Hiro nodded.

"Good. Because that's not all. Now's the awkward part." Tadashi looked away. Hiro rolled his eyes. What was so awkward about this? Tadashi still did not looked at him. "You know about your…?" Tadashi gestured at Hiro's pants awkwardly.

Hiro looked at his pants and unconsciously crossed his legs. "Yeah?" Hiro looked from side to side.

Tadashi did the same. "Well…"

Tadashi proceeded on explaining to Hiro what his 'parts' had to do with puberty. He explained what happens with the girls as well and explained what sex was. Hiro did not spoke a word during Tadashi's really, really awkward speech. Finally, he finished and Tadashi found the ceiling much more interesting than Hiro's horrified face. Tadashi waited a few moments and then looked at Hiro. His face showed pure horror.

"I put what in WHERE!?" Hiro shouted.

Tadashi nodded awkwardly, adjusting his baseball cap. "Yes." He spoke very quietly.

"And that's supposed to make me feel… good?"

Tadashi slowly nodded.

Hiro scratched his head. "And about those fantasies you told me… Did that ever happened to you?"

Tadashi slowly nodded again. Hiro grinned a little bit. "With that tall blonde girl from your college-"

"Shut up!" Tadashi interrupted Hiro while he blushed a little bit. Hiro laughed a little bit.

"Sorry…" Hiro looked away. "This is awkward…" He kicked his leg a little bit, looking at the floor.

Tadashi looked away too. "Yeah…" He stood up. "I'll just…" He looked for an excuse to get out of there. "I'll just go help Aunt Cass in the café." He walked down the stairs as fast as he could, leaving Hiro with his thoughts.

Hiro blinked. "I will never speak of that ever again."
