I'm looking for yaoi manga with a story that goes like this;

-Uke likes seme, but seme already had boyfriend/girlfriend, but seme is actually likes the uke too. So uke and seme like each other, but both didn't know about each other's feeling.

OR

-Seme likes uke, uke likes seme, but somehow seme tries to make uke stay away from him, by saying/introducing their partner to uke. whether it's for the uke's own good or any other reason.

Somehow, both seme and uke are unable to say the truth about their own feelings to each other because of reasons.
Anyway, it's something like these stories, or with a little bit difference.

And it had to be those bitter sweet one! You know, the one that make you feel like your heart is being stabbed seeing the uke gets hurt.
Just like, Kimi ga Inakeriya Iki mo Dekinai and Silence. Too bad the mangaka didn't continue this. :'(

Croquis chapters 5 and 7

Thank you.. I just read it, and dem, that was so sad
The seme chickened out before trying. but it was good.

I hope you can recommend me more of stuff like this, but with a happier ending
