@anifd Relatability is a bonus for me, I have to find a character entertaining or interesting before something like relatability can have the potential to be a factor in my liking of one. The teacher route in Kiss X Sis was the only one I liked other than Miharu's.
Purity and naivete both tend to be fairly interchangeable in Manga because of how overused certain archetypes are, in my experience at least. I find them both "pure" in the sense that they're empty-headed virgins with no noticeable depth outside of seeking pleasure and companionship from the MC, there's no real selfishness to their thoughts, it's almost like their "sins" are impotent, they lack weight, there's just nothing compelling about either of them IMO
I prefer it when characters show their humanity through vices, pettiness, having something they want out of life, goals, ambition, staining themselves and making the necessary sacrifices to achieve them, that kind of behavior endears me far more than any amount of rom-com fluff or SOL drama ever will.
I did not find your comment tedious at all, I simply wished to understand which of the women you liked if the Sensei wasn't to your tastes.
