Possessive seme but not in a bad way. Beginning parts with SOTUS training were cringed as hell but slowly it became better, even though it is still annoying it didn't bother me since i got used to it. The couple didn't get progress until 3rd volume so it was so slow and push and pull was annoying and again it bother me until last 2 chapters. So uke artpit is a head of engineering department of juniors and in charge of training the freshmen about 3 month. So the training was harsh and seme was against some of the harsh treatments. That's why seme and uke wasn't agreeing with some process. But eventually seme understood that why uke was harsh with SOTUS training.
