I think Mimisuke's request could have something to do with Monaka's difficulty to fit in with her team, we've seen this with Mimisuke in chapter 1, Ibuki with her former group. As obvious as that is (it'll be funny if I'm wrong), I wonder what it'll be, maybe to skip practice with them for once or just hang out? Figure out what kind of idol they wanna be and get in the same headspace.
Btw, why are the texts calling her Jimisuke? Mimi never played guitar on the show
As always, thank you very much for the scanlation!!
