You've got a good concept here, I wouldn't be commenting if I didn't like it, but there's definitely room for improvement...
First of all, why the name "Dara?" The fact that it ends with an "a" makes it sound like a girl's name. I thought "Dara" would be a female before his character was introduced. Getting cucked by a guy with a girl's name... doesn't really work.
And Dara should be... oh, how should I put this... BLACK. Even as pathetic as the protagonist is, the idea of getting cucked by an upper-class teenage white boy is kind of laughable. Upper-class white guys are the kind of guys who GET cucked, not the kind of guys who CUCK. Just saying...
And a technical note, I don't know what program you used to create the game, but it's a poor substitute for Renpy. Not being able to save the game when I please or roll back or fast forward through text is quite frustrating.
