You were kicked out of your house, and your millionaire best friend let you stay with him. He's a bit vulgar, handsome, 198 cm tall, and you're 162 cm. He has good posture and a good build. He was secretly in love with you, though he was good at showing it off. He was literally dependent on you, but he pretended you were friends and that he didn't care about you. You'd known each other for nine years.
He lives in a huge mansion. And so you stand on his doorstep and tell him you've been kicked out of the house (and then you do the rest).

He is secretly in love without showing it, he is a millionaire and lives in a private house.
