4-year old Hiro was chasing Tadashi around their local park in an autumn afternoon. Tadashi playfully would stop to stomp and kick the leaves towards Hiro to distract him and humor his brother as he enjoys to see him quickly admire the glance of the leaves with different colors. Hiro continues to run after his older brother until Tadashi notices Hiro's speed slow down, so he purposely slows down so he could catch up. Hiro catches up and softy tags Tadashi and bending over with his hands on his knees trying to catch his breath. "Tag!" The boy proudly says but is too focused on catching his breath. Tadashi knows that his brother isn't out of shape. "Hiro, stand up straight. Now put your hands above your head." Tadashi instructs.

He is young, but Hiro was born with heart defects causing heart failure. It can very difficult to handle a child so young to determine whether or not if he is experiencing less blood pumping into his heart or maybe worse. After Hiro's birth (and the loss of his mother during the labor), Tadashi was determined to be the best and a hard working big brother to raise Hiro. Their father won't be around to help them anymore; all the pressure of being the man of the family lands on him. "Hey let's take a break." Hiro nods and they both sit on grass. He starts to collect the leaves that surround him to make a pile in front of him.

"So, how was school today?" Tadashi asks his brother. "It was boring, no one know their colors yet, so we had to learn the colors all day!"

"Oh, so you think you know all the colors then."

"Yes, I'm smarter."

"Hey now, don't get too cocky yet bro. Thinking like that all the time will make you seem selfish and rude. Remember what Auntie Cass said?"

"Respect other the way you would like to be treated." Hiro said paying more attention to his leaves. "But I don't get."

"Ok, let's say there's somebody who can count to 100 and you can only count to 50, and as you are trying to learn the rest he purposely shows to you to hurry up and says that you're stupid." Hiro looks up, first, astonished by the rude insult he learned not to use and then took his brother's words to thought. "But I don't want to be...slow. I'm still trying to learn."

"And so are the other kids who are trying to learn." Hiro ignores the pile of leaves he created and stares at his older brother. After a while he spoke up again. "You sound like auntie. Talking like she's helping us with problems."

Tadashi knows Hiro is a bright kid. Whenever Tadashi learned or did something new, Hiro would always want to do the same. He wanted to be just like his older brother. Yet, he's only four and there's still so much he needs to experience when he gets older. Hiro still does not understand too much about his heart condition but he knows he needs to let someone know he's feeling sick or when his chest starts to hurt.

He goes back to his leaves to play with them as Tadashi thinks about how much he loves his younger brother. He would do anything to make sure Hiro stays happy and alive. He remembers he helped Hiro create an imaginary friend so that whenever he is alone he can feel like there's someone there. One day they were sitting by the Bay Bridge park. Hiro complained that he had no one to talk to at school because he was viewed differently in his school. Tadashi suggested why not create a friend. Hiro got excited at the fact that he can have an imaginary friend who he can create to make it like him. He had troubles creating the name so Tadashi suggested 'Max'. They both liked it, however, Tadashi felt there could be more than 'Max'. As Hiro rambled on about how awesome his new friend 'Max' would be, he looked out into the bay watching the small sail boats on the water as the sun was beginning to set. He loves his homeland, a place where it's cool and colorful as the Japanese cultural lifestyle continues to live through the city. Max should be a part of this city too. "Hiro. Why not 'Baymax'". "It's too long." "But I like the name Baymax." Hiro processed the name in his head. After that week, Hiro began to mention the name Baymax very time he came home from school to share to Tadashi the 'adventures' they had on the playground and classroom.

"Um, Nii-san." Tadashi leaves his thoughts. "Baymax says I have to take my medicine now." "Ok, let's go then." He helps his brother up and they head out of the park to go home. "Baymax sometimes is annoying, trying to tell me what to do. But he helps me remember."

"That's good little brother."
