well i am looking for a manga that the uke has stalker and the seme have to deal with him,the stalker can be a guy or a girl
thanks in advance

First one that comes to mind is Fan ~ There are more, I am sure.... but I will have to go through my list to find them.

Mendou Michauyo, ch3.
Mankai Darling kinda fits... but it's not the main "problem", more like 1~2 chapters.
Shitsuren Mania, I guess there is a stalker...
Can only remember these ones. If you want the seme/uke stalking is easy, but another stalker is a bit difficult.
Try Kidnap category, maybe it's more easy to find uke in danger+seme helping.

Akuma wa Hohoemu - not the main plot, but does figure in the story's outcome.

Cut by Kawai Touko. Also applies very vaguely to Koi ja Nai Kedo

hello, i was wondering about a manga i read a long time ago where the main charachter likes watching people ( gets turned on by it 😕 ). and one day one of his classmates notices that in some kinde of a park whre he teases him or something... it was definitevely smut so if anyone knows something pls tell me 🙂
as for stalkingtype there is :
Bukiyou de Gomen
Kyuuso wa Cheese no Yume o Miru
and Body Talk Paradox

people don't change, they just pretend that they do because life would be easier that way...excepte Pokemons, they evolve bitch!!
