I'm confused. Isn't sensei talking about giving up being a teacher when Samarun graduates? Why all the talk about her needing him there?
I wish there was actually some bonding episode that explained why Samarun feels so comfortable going to mother(-in-law)'s house. Also, yes, it's vaguely cute that she values sensei so much, but it's kind of depressing that that's the totality of her expectations for the future. Hopefully mother's guidance pushes her to 'grow'.
Thanks for translating.
