It's ok. there are ideas that are underused as a differential that, unlike most, the prota "yields" to yandere, and does not necessarily want to escape it. But it is only in the field of ideas. Sad.
But, I think her biggest hit is precisely the rhythm and atmosphere behind it, since the girl is disturbed, but the author almost always shows it as an emotional scene (OMG, look at what she does for love) or funny (kkkkkk crazy girl bro), which gives this atmosphere of "she is strange, maybe the limits have not been reached yet and that gives me".
Which is also the biggest shot in the foot, since you expect something bad, a plot twist, something bigger, but no. This "greatest threat", common in the Yandere genre, does not happen. Which gives a frustration and even a disappointment in the end.
