If this dude had said something along the lines of †žMy Students don’t schlick or go to the toilet“ I would have lost my shit...

Superb artwork.  The way Tsutsumi spreads herself
open (page 16, panels 4-5) is exquisitely well-drawn.

Critical Tip:
You can always spot a good artist--who's a real pro--
by the way he or she draws hands, and Okayu draws
hands extremely well, with great delicacy.

Perfect? Perfect!

I'd say he should be afriad of losing control of himself when they aren't in public, but I get it. He loves that exhibitionism tag too.

...if only she didn't pull away we could have had that tag here too. Guess I should be happy this has a vanilla tag I guess.

"I'm worried I might lose control when we're out in public"?
That's fine too, I mean, at least he's trying to be responsible in order to maintain their relationship, away from the judgemental eyes of society.
I mean he did eventually do it once with her before she graduated, but hey, it worked out nicely in the end. She graduates, is no longer his student and they can now freely date and show affection to each other in public.

Makoto-sensei barely dodged the proverbial photon torpedo (not just a bullet) by succumbing to Ai-chan's temptation when he did ... another time, place and artist, it could have gotten downright ugly.

Luckily, that hurdle has been crossed at last by the end.
