People are saying that the sensei only went for katou because he was lonely and all that but no, if he only was with katou because he was lonely, he should have put himself out there. He should have found another partner, givem that he is popular with the ladies but he didn't. Sure, Katou made so much effort just to make sensei like him, but I hope everyone knows that not all people will love the same way, even in a romance sense.
Also, kudos to this sensei for trying not to be a pedo and all, unlike most seme teachers that have no qualms preying on their students. Albeit, the mindset continues on when Katou is like 23 and he's 32 which makes it technically legal already. I love how he was still a bit hesitant about it because of his morals and what he's learned about from the past scandal in school.
Love this mangaka so much (●'◡'●)ノ
