This girl is a 100% keeper, she doesn't care for prestige fame or anything else, just want her beloved sensei to be widely recognized for his skills, instead of rotting himself away in the boonies.
And then marry him ( ͡° ͜ʖ ͡°)
I can't wait to see the other girls flashbacks and what their plans for Sensei, besides the marriage part of course ( ͡° ͜ʖ ͡°)
