This, 100%. I can't think of any game that is closer than a stone's throw from realism around here, but it is my pet peeve with VNs where every single female character is DTF with the MC, when they have spoken less than a dozen words to each other. Come on devs, that is just lazy writing. Give us as players some semblance of a reason why the LI is interested in the MC, other than the MC picked up their pen that one time in class. At lease give us a time-worn cliche like the MC saved the LI from bullies, or walked them home with their umbrella in the rain, or something. Better yet, show that they actually have something in common with their personality, some reason to be attracted to each other than just their mere presence.
This is what separates the devs with imagination with those just phoning it in. Give your characters a reason to act like they do in the game
