I don't remeber many of this type, but my favorites are:
1. Netkama punch: this one is really catching and is completed. MC is a tsundere and ML is a hot famous gamer. The premise is - MC was the master of a big guild, until one day ML took everything from him. With his pride shattered, MC decides to never play that game again, but the things never go as we plan and MC suddenly sees the opportunity to take revenge of ML in an unusual way.
2. The guild member next door: the funniest manhwa of this type. ML is a lost case, we like to call him delulu~, because he takes all the things MC does as signs of interest in him, while in reality MC is just trying to be a friendly neighbor.
3. I'm a Scarecrow: the story is pretty blend, but it's still cute. ML meets MC in an online game, MC is a really bad player (though it's not his first time playing that game). ML is an op player, so he decides to help MC to get better. As the time goes by, they develop a relationship beyond friendship.

here's my list so far
