Y/N is a normal college student. She works at a small cafe and is a history major. She doesn’t have many friends except her sister, Amaris. So, when Amaris finally drags her to a club to drink (semi illegally), Y/N is shocked to find a beautiful girl there who seems interested in her. Y/N is also yet to find out that this girl is Manon, from the sensational global girl group Katseye.
