About a student who enjoys soloing monsters/bosses and is a little crazy. one point he finds some fox boss out in the woods and ends up soloing it for a long time and meets a rare baby fox after and heals it. He also chose his game character to be some kind of golem. i also remember he meets a girl or two in the game and they end up coming to his house in real life.

hope someone knows the title please.
