:: He's on edge ✎⋆.࿔*:･ (it's not stalking nor stockholm sindrome tropes, but there's very dubious and questionable acts, trauma, and angst, je)

except moritat, but honestly that shit was so weird i dont even remember it that well welp

Warehouse
It has kidnap & r*pe but it is interestingly tied to their past traumas. And surprisingly has a happy ending. I think you'd like it.

Hwanyoung's Misery might scratch the itch for something like Killing Stalking, i think the raws are completed but the translations stopped being uploaded on here. But it's my favorite right now!!

Stalker's Game
Stalking is in the name haha. Has a happy ending and is completed. I really liked it!

I will add, though i don't know the ending for hwanyoungs misery it has my FAVORITE depiction of Stockholm syndrome I've seen so far and I think it's worth it just for that. It's so delicious.
