Arra looked very nervous, the woman didn't get a message from Kevin on time, even at dinner Arra was still waiting for a message from Kevin, just before. Arra went to bed the woman was still busy waiting for a message from Kevin for a long time.
Stupidly Arra doesn't have Irfan's number, if only that girl had Irfan's number, Arra could have asked her about Kevin's state, maybe they were studying together at their additional study place.
Unfortunately, that didn't happen, Arra didn't have Irfan's cell phone number for everything it was just an unpleasant hallucination.
