- All NPCs are in love for the protag
rev01
In the begginings of the immersive virtual reality age, a lonely guy develops a virtual girl to love him whole heartedly (in all the ways).
it works but her functions are too primitive
and so he finds himself unable to satisfy his loneliness, and lacking in talent to develop her better
Facing that reality, he abandons the project, but not before making its source code available online hoping it can help a lonely soul such as himself.
Unbeknownst, a company developing one of the first big immersive VR online rpgs end up using his code as the base for their NPCs. But by mistake they leave parts of affection code targeting the MC, and while they don't find anything wrong when testing before releasing the game, that's not the case when our protagonist joins it
Upon joining the game the MC suddenly finds all NPCs falling in love for him at first sight
girls fall in love and have their loins burn in desperate passion
guys differently, maybe because of the change in sex organs from MC's original code, only have a deep brotherly love and admiration for him, still helping him however they can, even by lending their more than willing girlfriends and wives to him
