Millians Yamamoto

This boy has been in the Main Cast ever since Aria existed. He is well known by old fans.

Personality
He is mature but the baby of the group. He is the most innocent in the whole group, and his friends want to keep him that way.

Meeting Ari
Mill met Ari in a class in 6th grade, they had a rivalry when it came to Pokemon. They dropped the rivalry when they agreed in 8th grade that the rivalry was foolish. When he learned about Ari's channel, he had no interest in it whatsoever. He learned he had an OC, and ended up liking it, although he wasn't fully with the tail design.

Aaron
They met in 6th grade and were friends until their 8th grade year. Things became awkward after Mill ound out Ari had a small crush on him. They don't talk as much anymore and are now just acquaintances, they still talk, but it's mostly greeting each other when they bump into each other. However, since his OC's been a huge part of the channel, Ari continues to treat his OC like a friend.

Ellie
It's unknown if they talk.

Evelyn
Evelyn is Mill's friend, outside of his friend group. They have each other's numbers and text each other sometimes. They talk once in a while.

Niko
He has been seen once blushing at Niko's flirting. But it was probably embarrassment. Ari has not confirmed if Mill has any feelings for Niko. But since Mill is asexual, it might not happen anytime soon.
