Or maybe it's just the blocked up dam bursting and emotion is rushing out.
After a bit of time she might calm down.
Although this chapter makes me wonder if the title might've misled us on who's actually the 'villainess/evil lady' (since Xiao Yang isn't part of the OG cast and is currently far more yandere than Dew...)
It might be more apparent later, but Xiao Yang doesn't really come off as Yandere whatsoever, moreso that her latent desire (with desire tends to come possessiveness) has been amplified to an insane degree with the erosion of her fulu, just like how her protectiveness caused her to almost skewer an unarmed bully.
Dew on the other hand 😒😂
Getting choked by the person you love and thinking it's exciting so long as it's a sign of affection...I think there's been a lot to hint so far that Dew is low-key nuttier than squirrel shit lol. I agree that we definitely haven't gone "toxic Yuri", but if we're being fair that's only because Dew hasn't chained Xiao Yang up in her bedroom...yet.
