"That would've been fine" Oh god I hope that's a thing when translating to english cuz oh dear who knows what's gonna happen otherwise. Maybe MC becomes crazy and kill her or something like that and then NTR her? I don't really think so, but it would be interesting xD
I doubt there's even a scant chance of someone sleeping on the commute also holding the adjacent person's hand. She's clearly okay with stopping being an idol, and clearly wants MC to initiate it. MC just needs to stop being a spineless sap.
