Sorry for the bad advice.. I didn't give it a second thought. Please don't contact the admins, They might have things to worry about. Sorry for being recklessly minded. I do hope you find the manga.. If this is a better option.. Try remembering the names of the people in the manga and search. Normally some mangas do come up so hope that was more helpful.
I have spent several sleep less nights trying to find these two mangas, but I couldn’t find it now matter what maybe a kind soul could help me find them
The first manga is about the seme being a manager of a hotel and then he suddenly gets transferred to another branch of the hotel where the uke who I think the ceo of the hotel was. The uke used to be a really innocent guy who knew nothing about the word fapping, but then the seme came to know about this and thought him erotic things and thus making the uke very erotic in the present
The second manga is about two guys a video producer? And a hairdresser getting invited to their two timing ex-boyfriend’s wedding.They both meet at a bar and you know what happens next ლ(´ڡ`ლ).
I hope my fellow fujoshis/fundanshis can help ╥﹏╥
