Nah, i think he'll probably blackmail him or smt like that
could be that idk, i just remember a chapter where they were exchanging the medicine
but it wasn't the teacher??? Wasn't the one who exchanged the medicine like a random dude??
wasn't there a chapter jiheon went to the teacher's house to talk? I know that kinda happened but idk if it was before the medicine
Ah yeah on chp35 or smth he got the medicine
from a weird shady guy, so the time the two ttalked was probably way before
im gonna throw a random guess and say Jiheon is gonna show up because they have a deal
