Meeting My idols

Wonwoo is a boy without a lot of friends. He is gay and the only one who knows this besides himself is his best friend Melanie. He love this one band called seventeen and his favorite in the band is Mingyu. After a Seventeen concert he is in a accident which leads to him living in Seventeens dorm.

What mysteries will he face there and why are they all so possessive? Most importantly why is Mingyu possessive over him?

There will later on (probably) be mature content, not in the start though
