I'm confused if this is shounen ai, as far as I know the author writes shounen ai too like Sasaki to Miyano.

BUT

If this is shounen ai, does Imari like Tsumugi? I'm kinda confused in the last chapter page (chap 17). I know they are just childhood friends but any I'm confused.

If this is shounen ai, then I ship Imari and Asahi more haahha
