He's your best friend since childhood, you're so close, you guys share everything with each other, you do everything together, you both care about each other very much, but one day, he got a girlfriend, you didn't care much since he's your best friend not a lover, you were fine with it but you felt a little sad because he spent more time with his girlfriend than you, then one day they broke up because his girlfriend cheated, he got so depressed that he even tried to kill himself but you didn't let him, you were there for him, one day you took him to cafe to cheer him up but he was just all the time looking at the rain outside, he was still depressed.
