After a bad fall, Lindi Shen finds herself in a completely different reality. Instead of the SM trainee that she thought she was, she is now in one of the top girl groups in Asia, the Romantics. Her once best friends Onew and Jonghyun, of the famous SHINee, now act differently. Lindi must go through some time with this new life, taking her back around every corner, every trial, just to help her remember every breath she's ever taken.

Junho is placed in the hospital after a terrible car crash. The car crash might have physically hurt him and his friends, but the memories of his best friend, Lindi, never went away. After hiding his love ever since they were young, Junho is finally ready to reveal his feelings to her only to find that while he was in the hospital, Lindi has had someone else claim her heart.

Lindi Xiang is the new girl in school. Everyone knows how that can be. Upon her first day, Lee Joon takes a liking to her. She's innocent. Him? Not so much. Just as Lindi begins to fall for Joon, he jeopardizes their relationship by going too far.

Joon takes notice of a girl practicing in the park. Her name is Park Akari EunMi. It was not an understatement to say that she instantly claimed Joon's heart. She practices Tai Chi regularly until one week, EunMi arrives with a strange sparring partner. The two fight in hand to hand combat leaving Joon speechless. As Joon demands why the girls need to perform this horrid act, a mysterious stranger hails him away. EunMi disappears. Joon hasn't forgotten her.
