It's unusual for a manga to honestly state that a male lead is good-looking. Maybe that's why he gets away with it.
Also, there is an awful lot of girls among that "nameless lolicon" crowd. I wonder if they are here for the onii-san, or if this is one of those VRMOO that allows cross-play. For some reason, these games in manga/novels usually don't allow cross-play, but IRL MMORPGs allow it freely.
