I think sensei is trying to say that they have a really huge gap and if they had a relationship, it would be forbidden by law since she's a student and he's a teacher. Idk why tho. Sorry.
I think sensei holds back since she's a student, his student. It is forbidden and can be a huge mess if he answered to her confession
That lesson is part of Japanese Literature for them. The life of Hikaru Genji is a famous literary piece in Japan. Also the whole illicit relationship about Hikaru Genji is a very timely thing too since I think that's him lowkey giving her a clue about what their relationship will be.
Thank you for the replies, it makes more sense now
I’m seriously confused. I feel like he just ignored her confession and what was the point of that lesson?? Can someone please explain to me what happened this chapter. ┗( T﹏T )┛
