My boyfriend is handsome and has a great personality, so he's very popular! Because of that, I'm really worried he might start looking at other girls. Even though I know Kenmochi would never do such a thing, I can't help but worry.
Then one day, for some reason, Kenmochi was invited to a mixer hosted by his company! I couldn't exactly beg him not to go, so I gave him permission.
Now, what should I do next?
When asked about his girlfriend by someone else (a man).
