(Let's say that Tadashi had introduced Hiro to his friends before the movie, because Tadashi is a big part of the story, so we can't have him die now, can we?)

It was a year before the movie took place, and Hiro was going through some hard times as a 13 year old boy. He found himself feeling uneasy around Honey Lemon, and sometimes even Gogo. Whenever either of the girls were in the same room as him, he'd smile awkwardly and not say much.

He knew why he was acting this way, he wasn't stupid. But he didn't exactly know what was going on. Why was he suddenly totally attracted to girls? Why was he so sweaty all the time? And most importantly, what was going on with his body!?

Of course, as the curious young boy Hiro was, he finally asked Tadashi what was happening.

"Tadashi, this may seem a little...weird...but I need to know what's going on!" Hiro said, clutching at his brother's shirt.

Tadashi turned around, confused as to what Hiro was asking him.

"What's going on?" Tadashi asked him. Hiro groaned, sinking onto the floor.

"It's embarassing." he muffled, his head buried into the clothes that was piled upon the wooden floor. Tadashi wasn't sure at first what he was getting at, but he soon realized what the cause of Hiro's troubles were.

Tadashi suddenly burst into laughter, he just couldn't help it. Hiro was just curious, but he just seemed so oblivious to the facts that everyone else seemed to know.

Hiro turned bright red as he saw his brother laugh. He picked up a heavy book on aerodynamics and started swatting it at his brother.

"Stop-laughing-just-answer-my-question!" Hiro yelled, swinging the book at his brother after every word. Tadashi kneeled over, laughing so hard that he couldn't even feel the book hitting him. Hiro threw the book across the room, frustrated that his attempt at getting his brother to stop laughing wasn't working. Tadashi finally stopped laughing, and stood up before Hiro.

He then explained what happened to the body and why he was feeling this way. It was a long lecture, and Hiro kept silent. Tadashi asked him if he was paying attention, because Hiro had not spoken or moved at all. He slowly nodded, but still seemed to be in a trance.

"Do you understand, Hiro? It happens to every boy...and girl, but it's different for them...did you get it?" Tadashi asked Hiro. The younger sibling seemed to snap out of his trance and look up at Tadashi.

"Um, y-yeah. I get it." he stuttered. For the next few moments, there was a very awkward silence. A knock on the door interrupted the moment.

"Tadashi? Hiro? It's me, Honey!" Honey said through the door. Hiro groaned as Tadashi stood up to open the door. Hiro did not want Honey Lemon here. She was the cause of his problems.

"Hey, Honey!" Tadashi greeted her. The blonde skipped through the door even though she was wearing tall hot pink high heels. Honey set her butter yellow purse onto a nearby stool.

"I came here just to check up on you guys. I haven't seen you in a week, Tadashi!" Honey beamed, hugging Tadashi tightly around the waist.

"Honey, you've seen me at the lab." Tadashi said. Honey sighed. "It's not the same at school!"

Hiro couldn't help but snicker at his brother being crushed under Honey's strength. He immediately regretted laughing, as Honey quickly took notice of him.

"Hiro! You've grown so much since I've last seen you!" Honey exclaimed, also hugging Hiro around the waist. She really had to bend down to hug Hiro, and it actually looked really awkward. And Hiro felt awkward. He started sweating. Honey Lemon, Hiro's ultimate crush was hugging him. He started blushing like mad.

"O-Okay, Honey. You can let go of me now...p-please...?" Hiro stuttered. Honey let go of him reluctantly.

Tadashi saw how Hiro blushed when Honey hugged him. His little brother really did like her.

And he knew what he was going to do with that information.
