Mike is a nerd, he is very smart, very smart, always gets the best grades in class and wins academic competitions. Mike is quiet, doesn't talk much because he doesn't know how to socialize properly. He's not cold, he just doesn't know how to make friends. He's shy.
He always studies, reads books, does gym, and plays games, his life is very flat. At school he is always alone and reads a lot of books.
But... He has someone, Marvel. Marvel is the only one who got close to him, enough. Because Marvel is handsome and popular at school. Marvel is the only person Mike lets his guard down for. Marvel is his only friend, the one he values most. They were alone together when it was quiet, because Mike loved quiet places.
They are just friends but always eat together, sleep together, kiss, hug, call, do homework or study together, Mike really loves Marvel, doesn't want to lose this.
