Please help me find the manga

When I first got into yaoi, I read a manga about a guy who was perfect and never had to be try to be good at everything. He designs a dating game one day and he has to test it, but meets a character there who he eventually falls in love with. In the end it turns out that it was some guy in his class who hacked into the game. Does anyone know the name to this? I've been searching for days and I'm so frustrated that I could stab myself with a fork :((
