Pretty dang good. The RL prologue introducing the character and why he ends up playing the game is brief but believable, its refreshing to see neither the lazy cliche "Everyone has enough disposable income to spend every day playing a game" nor filler chapters dedicated to RL just to make the story "realistic".
Character developments good so far too, slow in a good way, where we are told an appropriate amount of information about a character for how long the MC has known them (there's no "you saved my life so here's my entire life history and also my unending loyalty). Not to say the MC doesn't quickly form relationships(in a way that fits his character/personality), but so far everything has been progressing naturally.
The only criticisms I have are not knowing much about the MC's history, but I'm only on chp 14 so it could still be coming, or it might be more of a gradual reveal, either way I'd like to know just a bit more early on. Also, the world is large, and location names are kinda hard to keep track of.
If anyone is thrown by other reviews complaining about the sex, know it isn't really described explicitly(so far I've only seen 1 short instance describing the sex, 95% of the time its "they kissed and went to the bedroom", end paragraph, then "After an enjoyable night MC woke up" and its right back to the story). Also wouldn't describe it as "harem", he's not collecting girls for his adventuring party or anything, it's more like he's a warm, passionate guy(see fire affinity), and having casual sex in a no-risk virtual world fits his and others characters.
