I think he lost his memories like the dad from the princess from the dumpsters
Theres two childhood friends one of the friend (seme) needs to leave the uke bc of his dads work years later hes a highschooler now and he goes bavk to the town where his friend is when he goes to the school he ask the other students where the uke is and said "do you guys know (uke name) he must be rlly tall now right?" Or somewhat the same as that the other students responded to him "ehh you mean (uke name) hes been very pitiful these years as his extentive family took over their bussiness and his shitty cousin is bullying him he also hasnt grown much since you left here.." so he goes to to find the uke as they didnt tell him he find tye uke getting bullied by his cousin he defend the uke goes to the nurses office then had sex
