A lot of mmo mangas suffers from same shit.
The games that are popular in them always have 0 balance so if it was a real game no one would play it because how unbalanced it is.
The manga is set in japan.
Being gay there isnt as accepted as in the west.
These are other weird cultural differences when it comes to how people view cheating.
Just like when its boys where its not gay until balls are touching, its not gay until vags are touching.
Clearly hetero chapter and shes still not in to yuri.
