This movie is quite typical love triangle - quadrapple trope. But they nail with the good storytelling by the director and writers which make us hooked with twist and turn plus Kim Yoo Jung give her character so much heart and the biggest impact to the storytelling being successfully told. So even with two green acting from her leading man doesn't affected the movie to be mediocre. Though, quite underwhelming with the ending execution.

It teach us not something sacrifice for people we love benefit them.
