Another weird story? Didn't we had enough in this Anthology?
Although, I have to admit, it was kind of sweet that both girls understood(most of their time) each other without a word, but sometimes is necessary to voice(or something similar that can be understood as consent) what is in going on a person's mind.
Nevertheless, if the other girl didn't reciprocate the MC feeling's, then it would be quite problematic. So, please for all that is holy, don't stalk anyone, it makes any person look like a creep.
