Knowing the author, it's probably a bait and switch again, and the flowers are for someone else.Well the flowers have to be for Aya, no?
No, she needs to go to the party. This is for her future. Aya can and will wait. No need to blow a once in a life time opportunity. Setup is she will probably leave the party early and will join aya at the promAND THE CROWD… wanted mitsuki to do same thing w aya?? when i first saw these panels in japanese i thought “ she’s finally going to get aya” but no, she was just encouraging joe😃
I dunno, maybe they were first intended for the musician party, but I could very well imagine, that Mitsuki dramatically arrives at the prom and hands the bouquet over to Aya.Knowing the author, it's probably a bait and switch again, and the flowers are for someone else.
