Looking For Yaoi Manga

I'd like recommendations for any yaoi manga/manhwa that has the bigger/taller guy on bottom and/or has them switch even if they have distinct body shape differences. I'm not picky about much but I'd like consent, decent art, no underage/shota..

Anyway if anyone knows of any big boys getting topped, let me know! That's it, thanks!

Hi, I'm looking for an office worker x boss story
The story begins with the uke going to a gay bar, broken hearted because his best friend and unrequited love is getting married. He meets Kou, a weel known guy in the bar just coming back from the USA, sleeps with him and discovers the next day at work that Kou is his new boss transfering in the japanese branch office.
They start seeing each other until Uke understand that Kou is only playing with him while Uke fell in love with Kou. Uke is being transfered and Kou is starting to get sick because he finally understands that he was in love with Uke and try to get him back.

Does it ring a bell to anybody ? ┗( T﹏T )┛
