Love Untangled

Busan, 1998. High school student Park Se-ri, who has vowed never to be the first to ask a guy out, decides to break her rule for the sake of the school's handsome guy, who is the object of affection for almost all the girls. To prepare for this important step, she needs to straighten her curly hair. The only salon that offers this service is owned by Park Yoon-seok's mother, the new classmate who recently broke his leg and almost drowned. Se-ri agrees to help Yoon-seok in exchange for a free hair straightening treatment.
