We're going into a weekend, and I can afford to miss cram school for something like this.

[ "Something like this" being "an acquaintance got trapped in a haunted theatre." ]

Obviously, I can't stay here the entire time, and I'll need to leave in the first place in order to promote this show, but this isn't your responsibility to bear, Tenma-san. You weren't aware any of this would happen and you've been trying to protect me from getting too caught up in this the entire time.

[ From trying to get her to leave to making sure the ghosts didn't see her. ]
