Have you ever imagined; going to a summer performing camp in a completely foreign country with your best friend (Jang Wonyoung), your ult crush at school (Kim Minjoo), accidentally grouped with two other students with similar names (Go Yujin and Heo Yunjin), and has a doppelganger-like university student as your mentor (Takeuchi Miyu)? Ahn Yujin can relate.

Minjoo came to spend the holiday with her sister Hyewon and her new family, there she met Hyewon's step sister for the first time and couldn't help herself but thinking Chaewon hated her because of the latter's narrowed gazes and poker faces.
