The only way to be official is to end the act.

Any guy who reads this shojo manga ought to be a good guy.

a better arc lol

Age is just a number for Japanese, mature indeed.

Daiki bro.

Smoking in school, gigachad.
This man is messed up. Creating a mistrust issue in a 16 year-old girl in her first love.
He should do better to take bigger blames than denying his love for her. Explains everything humbly and politely drawing a fine line starting from there.

It's a feminine biological instinct—the point when the teacher quits teaching for her is the point when Suzume will stop liking him.
It's not manly at all to make such a move because teaching is his duty and calling. They're viewed as being possible, not filial in their important responsibilities as dads or husbands in the future.
Is he quitting for her, or did he break the code of ethics.

Teacher should quit his current school.

Mamura has some guts to dislike a homeroom teacher.

I know Daiki will emerge as the winner; otherwise, this manga would have been famously under flaks.

as a father to be, I'm rather displeasured with such adults.

Despite 'disliking' the opposite sex, Mamura gave a proper, mature rejection.
Because of such choice, that person doesn't feel overly bad, ofcourse she's still rejected.
10/10 move. Not even grown-ups can do that properly.

with that suit, its gonna be hard buahahaha

The second lead is right on point; you don't mess with your student's private life.

I'm sure sensei felt almost nothing reading the letter. He had his feelings sorted out with no loose ends.

Not giving a proper break-off is a bad choice. Such characteristic is not the ideal, at least at that time.

Grats, what a brave girl.

this is smooth 10/10
