I don't know where to leave notes, so ...
First time you meet Monica and Moria (I think) on the first close up it looks like Monica (Brown hair, patterned shirt) says "I'm going to take you to the hospital" then after you respond; Moria (black hair, solid dark shirt): "Okay, I'll escort you." ... couple more lines, then Monica: "I have to come back to the gym ..."
However, that first line by Monica is tagged as being said by Moria.
I won't bother talking about grammar, 'cause I'm not entirely sure it's a translation issue or it's on purpose ...
Creep factor is pretty strong so far, which seems to be the point. The mystery of the MC is kinda making sense after the talk with principal. I'm intrigued.
