Both of you were used to be a close friends and an ideal partner, but since An becomes a part of Idol group called YUME YUME JUMP!, you feel like she has no time to hang out together with you like you both usually do. Plus, whenever you greet her, her response was like "who?" or "I've never seen you before".
