WARNING: Mc's Ex cheats on him in the past and it's set up as a vital part of his character development. If that upsets you, then skip this game!

If not then: I highly recommend this one. It's about an aspiring film student who has his Ex cheat on him with his "best friend," and uses that to basically try and "become" someone else. He tries to force himself to be the "funny and confident guy," someone who's more socially active, talkative, and confident so that it never happens again.
