Hi everyone! I want to tell you about how to be able to call all three girls to your room at night, because it took me to beat the game to understand this. To do this you need to find three business cards for each girl. Sarah's card is in her classroom, upstairs where the red bell is, the card looks like a pink card. Linda's business card is at her work in her office, on a brown board with papers. Caroline's card is in her store, according to the meme in the second room, but I could be wrong, since I found it very first and forgot where exactly, but definitely in her store. I hope I helped someone.
