Pls can someone help me find this bl manga where everyone at school finds the uke pretty and the seme is quiet, has dark hair and likes animals. I don't remember much of the story line but the uke starts liking the seme first and the seme spends much of his time in the science storage room where he looks after animals at school. He also compared the uke to a cat.

The manga that you are looking for is called Sono Koi ni wa Wake ga Aru.
