The pills likely fell underneath the washer, since koogi drew it from that angle, where we see bum. The missing pills are *maybe* there and sangwoo is paranoid now that he counted the pills once again. He's puking cause he believes bum poisoned him, alludes to previous chapters of sangwoo's mom doing so. Although we didnt see them eating, its just a slight time skip since koogi must have thought it was going to take too many panels to draw...
I think sangwoo is hallucinating, like how he hallucinate that bum was in the car with the girl. Do u guys think that sangwoo ate the pills without knowing he did it himself? Cos it didnt show them eating food so theres no way bum could hav poison him..
