Ye Fanxing was kicked out of the house by her patriarchal grandmother and lived on the street penniless. When she was desperate, she was picked up by Jiang Yu, a "cold academic" from the same school. For the first time, he offered to let her live in his vacant apartment on the condition that she would be responsible for three meals a day. Living under someone else's roof, Ye Fanxing was careful, but found that Jiang Yu looked cold on the surface, but was actually a waste of life. He could even cook instant noodles and burn down the kitchen. The two went from being respectful to each other, to trying to undermine each other, to having a perfect understanding. While Ye Fanxing earned money for tuition by making handmade desserts, he helped Jiang Yu deal with the pressure from suitors and family. Ye Fanxing was shocked to realize his feelings when Jiang Yu was asked by his family to marry him, but Jiang Yu had already rejected everyone for her.
