Hey Trejon,
I get what you're saying. One thing that's easy to forget is that everything in the last update takes place over roughly 4-5 hours . Considering the performance itself (including all the preparation beforehand) already takes about an hour, there actually hasn't been that much time where Mina and the MC haven't had a one-on-one conversation. So don't worry, I'm pretty sure Mina still loves her boyfriend <3
