Overview
Se-joo is torn between just pretending to like Seol or really having a feeling for her. The dilemma all starts because Ji-no asks Se-joo to be around her to protect and care for her. Se-joo needs a story to write, and Ji-no wants to get closer to Seol. They end up writing a contract to settle their needs. Se-joo feels awkward because he does not know how to act around Seol and makes her upset by saying the wrong things.
