Looking for this trope BL novels

Real Yanderes only please. Ones that actually scare you (kind of like the ML from Unchanged Man).
Someone not afraid to confine their beloved.
MC can be the yandere or the ML.
MC can be the top or ML can be the top.
Even better if there’s a runaway arc.
Even better if it’s omegaverse/ABO.

You are free to suggest else.
