Basically seme was into uke who was the school whore that slept with almost every guy and when seme approached uke about how fucking random guys wouldn't make him feel loved uke acted out and locked him in a cage with a dog. Uke threw the key in with the seme leading to the seme getting bit by the dog.

Seme returns years later going from beta male to alpha male. Uke is still a doorknob that everyone has used. Seme approaches uke for one night stand and locks uke in a cage in his house where he fucks him and makes him his bitch in return for high school. Uke does not remember who seme is or what he did to him.
