Who Are You: School 2015

Sakahira Riku, a first-year high school student, is jokingly pushed on the shoulder by his friend Tasaki while swimming by the pool, and falls into the pool with Mizumura Manami, who is next to him. The next day, when he wakes up, he finds that his body has been swapped with Manami's. Both are confused and try everything to get back to normal, but nothing works. They are forced to desperately exchange information about their families, friends, club activities, etc. in order to play the role of each other.

Kim So Hyun shows her excellent acting skills, while also portraying an almost typical high school teenager girl, with added problems including bullying and the loss of a loved one.

Twins, one of them posing as the other one. Seeking revenge, uncovering truth and trying to find who hurt, bullied their twin.

Totally not the same, but both are melodramas with bullies, murder, and mysterious pasts in their plots. Both have Kim So Hyun in them, and she's always fun to watch. Truly talented young lady. Missing you is a lot darker and bolder but both are super interesting and hard to put down.

They both are roughly about people getting switched places and having to live their life. they both have that funny and nice second lead that everyone loves. both have that mysterious vibe and are great high school romance dramas.
