People come on..

They are 5 years apart and didn't even start anything remotely sexual until about 6 months away from the seme being a high school graduate and beginning college student. They were friends before they were teacher and student, and they were teacher and student for a max of like a year!! And let us be honest, if your childhood friend became a teacher at your school and you know you'll be graduating in a year, there is no way you are seeing them in an authoritative light. You are more then likely gonna follow the rules because you respect that they need to be professional at their job and you don't want to make them look bad, but they are definitely not giving you the same feel a normal teacher you know as ONLY a teacher would.

High school graduation age in Japan is 18, meaning the seme was just end of 17 years old beginning 18 years old before they even met up again and the uke was around 22 to 23 years old. What are y'all reaching for? Did anyone see the uke make an inappropriate move on the seme when he was younger? I didn't. There wasn't even the weird clip of the older childhood friend finding he was sexually attracted to the younger one when they were smaller and mastrabating before freaking out and then running away without saying anything. Even if they both realized they had feeling when they were younger, it was cleanly done with the uke exiting with the excuse for college and coming right back when the seme was of approiate age. There is ABSOLUTELY nothing wrong with this age gap. The story was good, compared to a shitload of others. If you don't like it fine, but let's not inflate things that really aren't a problem~
