Yaoi manga that I can't stop thinking about

Hi everyone. I hope you can help me with this. I've read this manga ages ago and want to re-read it but I can't remember the title. From the fragments of my memory, the plot went along something like this: the top is associated with a delinquent school while the bottom is from a reputable school. The catch is that the school is only divided by a fence. I don't remember if the bottom was threatened or not but I think the bottom started bringing food to the fence for the top. I also remember, I hope I didn't get it mixed up with other yaoi, but the top was strong with almost animalistic strength or something like that. If you know any yaoi that's familiar or if this sounds familiar please suggest the title. I would appreciate it.
