Hold on, are you saying the seme had a crush on his cousin?
Yes, he has an older cousin who had cats.
Yehey I found it.

I've read this yaoi/shonen ai manga long ago. The uke found a cat who looks similar to his previous cat. He had a crush to the owner of the cat. The seme is the cousin of the owner of the cat and also had a crush to the latter. Uke and seme were rival at first but then they fall to each other.
Thank you.
