The one who helped her not being the ML but someone else (his older brother) was foreseeable, unless there is another twist in future chapters and it turns out it was the ML after all. I also see we have a bigger cast than in furifura already; it reminds me of aoha ride. I really like the childhood friend, by the way.
Now, onto the MCs... I like Saku a lot so far. She feels different from Sakisaka's other fMCs and I tend to like characters like her. The ML, though... we will see, because so far he is too typical. I have seen the "stoic guy who pretends who doesn't care but actually does" too many times in shôjo. He is making me appreciate Rio and Kazu from furifura a lot more.
Main problem is the number of love triangles I can see forming in the future.
