I don't agree with the trashcan part.
I find yanderes interesting and sometimes you can find fluffy (half) yanderes who never cross the line.
Sometimes you can find gold dust in sewage, but that doesn't means sewage is full of gold
Sometimes you can find a healthy burger joint, but that doesn't means fast-foods are good for you
And sometimes, very rarely, you find a fluffy yandere, but that doesn't means yanderes don't belong in the trashcan
Also were exactly are you drawing the line that is not to be crossed? murder, assault, coercion, hazing, gaslighting, blackmailing, humiliation, intrusion, stalking, surveillance, verbal abuse? what level of disrespect are you fine with that you think oh she is not crossing the line, it is all good, she just loves him that much she has to step over him
I gotta ask because you are sounding kind of crazy here, yanderes are way worse than tsunderes, and tsunderes are quite trashy already when it comes to crossing the line, just this chapter you yourself agree that this girl humiliating the MC by making him look like a pervert who harasses women, and then hitting him for accidentally walking on them changing was too much, and yet Yanderes do much worse for way less
