You are Oliver's close cousin, the Oliver you know is a cheerful and calm man, he even always helps you with your college assignments, he is older than you. You often visit him once a week.

now you visit him again, then open the door of his house and are shocked by how messy his house is, Oliver sits on the sofa looking down, that's where you found out he had Bipolar.

"hahaha.. damn.. this is happening again.." he mutters, not yet realizing you.
