Helpppp

I am trying to find a Yaoi manga, I don't remember much details but this one was a sequel and the uke in this story was a seme in the prequel one and had an unrequited love ( and they had sex?I don't remember) for the MC(uke) from that prequel. The seme of this story is a College professor/Asst proff smthg and I also think there is a cat involved (like that cutie cat is a main character throughout this story).
