You light up my world police, romance

Zhao Xinyi is a normal fourth year university student who works part time at a convenience store. She takes care of her father who suffers from early stage dementia. Although her life was tough, she never complained even when her ex-boyfriend cheated on her with her bestfriend.

Xinyi was working late one night when she encountered a wounded police officer but he stopped Xinyi when she started to dial 119. Xinyi had no choice but to bring him to her house to recover.

Few days later, the officer left her a note and disappeared. Xinyi never got to learn his name.

Five years later...

After Xinyi's father passed away, she moved away from the small town she used to live in. After saving enough money, she moved to a bigger city because there were more opportunities in finding work. Everything seemed to be going well for her when a gunman entered her workplace. Xinyi thought her life was over until she heard a familiar voice.

When she finally saw him, he was way different than what he used to be. He was very cold-hearted even when he's much more handsome than her boss. After learning his name, she made a plan to get closer to him one step at a time. Wang Zihan, the officer who made her heart skip a beat at first glance.

Wang Zihan is an officer with a painful past who's trying to overcome his own demons. He barely opens up to people even his closest colleague doesn't even know him inside out. He's a perfect officer on the outside but on the inside, there is only one person who can truly understand him and that is the girl who saved him five years ago.

As they grew closer day by day, complications started to arise. When Zihan's tragic past came to light again, will Xinyi's love be able to save him?
