You forget that the MC's room has external access from outside. Blinds drawn and door locked. No problem anymore. Josy could also have the room key from the MC.
It's not ridiculous because DPC itself brought it into the conversation in EP6. Ergo, he could have already toyed with the idea. There could also be another option if Josy, Maya and the MC get their own apartment not far from campus. Would be an interesting option.
I repeat myself. A woman does not have to stop studying because of pregnancy. My mother studied and was pregnant with my older sister at the same time. My mother graduated without interrupting her studies.
Yes stepsister. But that is not the point. If you need distance and peace from someone, then it makes sense to stay away from close friends and family members of the person, because otherwise you will be reminded of that person. In order to clear your head, you should avoid being reminded of this person. Therefore, it is actually beneficial for Heather to have a room to herself.
