In Time With You- New Enemy

When Ariel suffered in the betrayal of her boyfriend, Bolin accompanied her for 5 years and Ariel eventually (seemed to) walked out from the shadows. However, the big bad demon is coming back. He is David. David has encountered difficulties and understood the snobbery in society. Therefore, he's back for Ariel. He found out that he couldn't leave her, because she's always a book that worth to read over and over again. Although David once betrayed and left Ariel behind, he decided to treat her with true love right now. Through five years of training, Ariel is now an excellent and confident modern girl. She has prepared for five years in order to prove that she has become a butterfly, instead of the caterpillar who was beguiled and bewildered by David. Anyhow, the moment she knows that David is coming back, her heartbeat becomes irregular and sporadic. She pretends that it doesn't matter but her daily life is strongly messed up because she's waiting for David's call every single day. Bolin understands Ariel's true feeling and observes every unusual action deeply in his eyes. He feels anxious and concerns that Ariel will hurt by David again. This time, Bolin is going to confront David and protect his love.
