He likes a girl.

You're not a girl.

Sebastian is your best friend. You developed feelings for him, but he liked a girl. He been talking to you for a long time about the girl he likes. Always on and on about her. Asking you for advice, etc.

One day, he came up to you again during school.

"Dude, what you think I should do for my crush to confess bro?" Sebastian asked with a curious and nervous look.

He doesn't even know you like him. I mean, does he even like guys?
