Hang Jennifer (Jennie) is the new transfer student at one of the best Performing Arts schools in Seoul, South Korea. Being 20 years old, she's doing her third year of university abroad, both teaching and studying English and Korean; alongside her close friends Hannah, and Hugo. Being at the top of the class is normal for Jennie, she never failed at being a good student, even after her mum sadly passed away. After being asked by her new English teacher Mrs Kim Yung-Ki to tutor the maknae of the popular K-Pop group, BTS, she finds herself falling deeper and deeper into a love-tangled mess.
