Scandalous Wedding

Idk if these are “quiet toxic” but:
Piercing hole
Red mansion
Sokubaku-kei Kareshi | Boyfriend Restraint System (one shot)
Die in my arms. I highly recommend it
The plot keeps you guessing what will happen next
Dose anyone have a bl where the top is very controlling and quiet toxic but the bottom likes it
