I believe it was a collection of stories or by the same mangaka i dont remember, but i remember 2 of them which paired a celebrity and some dude (i forgot his occupation) this dude saved the celebrity who was about to commit suicide and the celebrity became obsessed with his savior and wanted to be with the dude. The celebrity turned out to be a big M at the end while the dude was spanking his ass as a punishment for doing something
The second one was a big adult man and a small highschool rich teen. The man caught the kid stealling soemthing so he stopped him. Then he helped the teen. The teen became obsessed with making the man his. The teen is the seme and the adult which is twice his size is the uke.
I read this manga a long time ago and im trying to find it again. Please help ╥﹏╥
Not sure but maybe this one?

Its been 7 yrs bro and he had always reassured his feelings for moogeong but when it comes for Yohans insecurites he has never gotten a real "i love you" or "i like you" from him but rather he agrees to whenever yohan ask if moogeong likes him even when they fought moogeong didnt say his feelings confidently (recent updates)nor did he even hold any eye contact. I get that he is shy but to just brush off Yohan's insecurities like that without rlly trying to reassure him was just so heartbreaking too me </3
