As of now, no, they're in highschool but will be graduating in 2 and a half months as of now (i belive it was 3-4 months at the beginning of the story, so maybe by 40 chapters they'll be graduating?) But if its because of the yaoi tag that makes you feel uncomfortable they don't really do anything
do they get out of school? do we see them as adults at some point? just cyrious bc im not really into high school plots but this seems really good
