On an unrelated note, it is pretty easy to forget how to tie a tie. Like I have to look up half-Windsor every time I try to tie it. And the self-releasing one isn't the first result either.
Y’know, the unsaid thing is that Takagi must’ve learned how to tie a tie specifically so this sort of situation could occur. Imagine Takagi looking up how to tie a tie and practicing by herself the day before their graduation or something.
So even though he (subconsciously) knows how to tie it, he still has Takagi do it? Does this finally count as a win for him? Although I guess the fact he started a family with her means he's been winning for a while and just never noticed.
I can relate to this. I'm complete garbage at tying a tie. No matter how many times I try, I can't get it right. Even watching other people do it and explain it, it's in one ear out the other.
