Can you please help me? I spend 2 days looking for it but it hard to fond? Thank you

I am looking for a yaoi manga which the main lead is gay uke, the uke always have a fake smile on his face, his eyes are closed, he wear a suit, he sleep with a seme he found in a bar or gay bar , the seme has a ring on his finger and he told the uke that the ring is just to keep women away but later the uke discovered that the seme is divorced. And at the end he will give the seme a ring. The seme kind of like the uke and want to make him loves him but the uke is kind of cold( at first). I thing it is part of some manga yaoi and it's only one chapter( not sure)
