Please help!!!

I've been looking for a certain manga since forever. It's a little hazy but I think it's a side story in a manga. The uke is bullied by the seme because the seme likes him and the uke knows. The uke thinks that the seme is cute so he doesn't say anything. Then one day a transfer student came and scolded the seme for his pranks/beat him up ( i don't really remember) and the uke gets pissed off at the transfer student for interfering. I would really appreciate it if someone helps me find this.
