Imma recommend this one, "The Maniacs are Obsessed With the Fake."
I've read the novel though only half since raws stopped updating (still crying over it) and so far 2 obsessive and 1 is a lowkey or full-blown yandere (not exactly sure, just read up yo the point of him intending to kill other male leads). It's also an interesting read.
Adding this right now!!!
"The Young Master Hides His Chest" check out this manga. Its on this site and ml is kinda yandere. He hides his body with ilusion to remain fl type, stopped taking medicine aa kid just for fl to keep on visiting him. He is crazy but like in cute way, not toxic way
ദദ ˉ꒳ˉ )✧ thanks for telling me babe. He matched my list of course I'll add him (∩˃o˂∩)♡
