I get that the whole grand music gesture is clichéd, but I wouldn’t go so far as to call it cringey.
The running theme throughout this entire series thus far is the fact that music plays a huge part in Aya and Mitsuki’s communication. It actually makes sense for the grand gesture to be (if we are heading there) to be Mitsuki playing for Aya, especially if it’s going to be an original song because it’ll tie in to the whole Finally Mitsuki is Going to be Honest About The Way She Feels.
If this arc (hopefully it’s an arc and it’ll have a continuation past this point) ends with Mitsuki and Aya’s repairing their “relationship” / striking a friendship at the end of the school festival, I won’t be mad. In fact, it would be less genuine for them to go from this point of their relationship and and the current conflict into romance after the grand gesture.
It’s not wise to start a romantic relationship when it’s preceded by deceit that culminates to one of the parties being genuinely hurt by the deception.
So, yeah.
Arai Sumiko is single-handed my fueling my will to live. I hope she continues writing Aya and Mitsuki’s story because it’d be nice to have another few chapters worth of an arc of them working in their friendship and then having that arc culminating into the start of an actual romantic relationship ,, and so forth. It’d just be nice to have these compiled in volumes of manga where each volume explores a new stage in their relationship
