Umm how old are uke and seme supposed to be??

They went to the same school at the same age. If we assume the kids did 4 years of college and not graduate program, then most kids graduates at 18 from H.S. so 4 years undergrad, then graduated at 22. They knew each other the last year before graduation. So if four years undergrad then 22. Then plus five years later then 27. Both of them.

If you factor in grad school, then add a couple more years, depending on the program.
