I read it a long time ago so I forgot. It's about a guy creating a video game/virtual world and he fell in love with a guy in the game. In the end, the virtual guy disappeared from the game but he's actually a real person so the MC met him in real life (they're even go to the same uni.) Thanks guys!

I've been wanting to know this manga for sooo long. I think it's a shounen ai oneshot, where a guy is really depressed with his life and almost about to jump on train rail. Then he got stopped by another guy (stranger) that actually just got dumped by his boyfriend when he was actually about to propose him. This guy then took the depressed guy (who almost commit suicide) to hang out, almost like a date, and in the end he took him to a fancy restaurant. In the restaurant they talked about their life or somehing, then the stranger guy gave the depressed guy a ring (the ring supposed to be given to the guy's ex boyf).
Sorry guys it's so long and might be confusing, but please help!!!
