Kanna was pretty flirty on their crepe-date, spoon-feeding and all, and the artist chose to draw her in jealous yandere mode after she got suspicious, hidden eyes and all. So text and meta both suggest gay feelings for the MC.
Eeeeeh... I'm not really feeling this chapter. MC's friend wasn't a real character but rather a guide on what MC should do up until now and suddenly she's in love with MC? And she still understands everything for no reason. I don't know man, the character just doesn't work for me.
