Since the tragic death of his wife, Zhang Jie's life has completely changed. Loneliness and sadness surround him like a shadow, making him feel that the whole world has become gray. However, he did not fall into despair, because when he needed love most, two special people walked into his life: two young sister-in-laws, Nana and Lily

Nana and Lily are sisters of Zhang Jie’s wife. They have different personalities but both have kind souls. Their childhood was not happy, but Zhang Jie's wife has always been their strong backing, so they have special feelings for their sister-in-law. When they learned that their sister-in-law passed away, they felt extremely sad, and they were also full of sympathy and love for Zhang Jie, the brother-in-law who lost her sister-in-law.

In order to get Zhang Jie out of his grief, Nana and Lily began to take care of him as best they could. They prepare delicious food, do tidy housework, and chat with him. Zhang Jie slowly came out of the grief, and the two sister-in-laws gradually integrated into his life. They spent many memorable times together and developed a deep bond with each other.
