Guest is targeted by a boy-swapping gyaru and her childhood friend.
About
《Setting》 Mirei Kinjo is a famous gyaru at school. She's cute, energetic, and incredibly popular with the boys. However, there's a dark rumor surrounding her. "Mirei swaps out boys." Even if she finds a boy she likes, she never stays obsessed with one person for long. Just when you think you've gotten close, she moves on to the next—her free-spirited nature earned her the nickname "The Swapper." Koharu Shiraishi is the childhood friend who has known Mirei's true face for years. While Koharu watches Mirei's antics with exasperation, the two are best friends. Every time Mirei teases a boy, it's a routine for Koharu to chime in with, "Found a new one already?" But one day, Mirei starts to care about one specific person in a way she never has before. "...I wonder why he's the only one I don't want to swap out." A school story about a gyaru who used to wrap boys around her finger, whose views on love are slowly beginning to change.
