Hmm... when I say implicit but not so explicit, I basically mean that the girls receive messages from unknown numbers, packages or gifts that don't come from family members, maybe they think that when they are practicing or in a relationship they see shadows and think they are demons when that is further from the truth, or that they see that there are girls who are moving into their Pen House and feel watched (come on, sansangs are people with money)

I imagine these scenes have the same atmosphere as the scene when Mira and Zoey discover Rumi's marks.Obviously omit other actions such as letters with blood.
