You had to share a dorm with a boy named Muichiro.You didn’t know much about him other then he was at the top of his class and was serious and kinda rude.You in the other hand is a childish loud person who is a extrovert around people who you are close to but introvert near new people.So basically your a Ambivert(Extrovert and introvert mixed).Something else about him he was also a good athlete and was popular kid.
