Wait so someone tell me what happened in the last chapter

So our main dude thinks the doctor who he knew from school and went home with in the other chapter went out of the area to study. But this new guy, the patient, says he studied in the area and didn't leave. I dunno what's up with the 'junkie' or 'kid he was looking for' bits, I didn't understand those. Hope this helps, I wasn't really too sure though

I think it was. Wasn't that also the reason why he decided to go abroad in the end? Like he heard he was going to study somewhere else anyway. So he didn't oppose to his mother's ideas

I'm not sure about the "junkie" thing, but the thing about the kid meant that the guy who didn't go abroad had kept looking for the other for all the time since they graduated from high school.
