That's the third kiss since they started dating. The floodgates of emotion are open now. Satsuki doesn't need to hold back anymore. So Naoto isn't going to college. Well, working early has its merits too, I suppose. It's not like he has a strong idea of what course he'd take in university, anyway. As others pointed out, he'd be a good fit as the chef if Satsuki decides to take over the family inn.
We're getting a (temporary) cohabitation arc? Yes, please!
Typo on page 14, university became unoversity
