There's a spot somewhere in the second labyrinth that has a differently colored heart, which Elizabeth wanted investigated. She suggests that there's someone in your group that knows where it is. When you exit the Nurse's Office, you'll notice a new Stroll available.
Choose that and you'll see Yukari and Naoto talking about the area you need to investigate, with Yukari mentioning it's on the second floor of Group Date Cafe, near one of the rooms where you were asked a question. Note that you will have to bring Yukari with you when you go into the dungeon, with the spot being the exact place where you received the request.
