Good for you Sayuki ! Fuyuki has gain a lot of points with her "I'm leaving (for 2 weeks omegalul)" fake out, where Shiki realized how much he cared about her, I'm excited to see how it will turn out. I already see a lot of F in the chat for her, or that the legendary denseness of a MC can stall inevitable progress but honeslty Shiki has been pretty great so far.
I already said it in the piano chapter, but like other great romcoms like Kagaya or 5-Toubun, you really get why the girls fall for the guy, I have faith in the author too.
