Two complex people in a long-term relationship, unsure of whether they truly love. Hyunjin is focused on the process, and Yeji is focused on the result, and often their conflicts arise from misunderstandings, trying to take a leadership position. Hyunjin is quite a creative, sensitive and gentle person who perceives the world from his own point of view. Yeji is a more purposeful and focused person, she is a perfectionist, and does not accept her own and others' mistakes.
