One is calm and reliable, the other is arrogant and stubborn. When they first meet, they are full of wariness and tit-for-tat. They get along with each other in a humorless way every day. From disliking each other to tacit support, they gradually develop a love for each other while laughing and joking, and work together to resolve family tracing and career crises. This unexpected cohabitation will eventually become a sweet love that goes both ways.
