Ji Xihe, an “unreliable” therapist, falls in love at first sight with Jiang Xinghui, an astrophysics PhD with a hidden identity. He reins in his wild, carefree ways and boldly launches a “gentle campaign” to win over the person he likes. The very first day after he succeeds, he sweet-talks Jiang Xinghui into moving in with him. What begins as love at first sight gradually deepens as they get to know each other. Ji Xihe discovers that the person he brought home is a “little wolf cub” with an extremely possessive streak, but every side of him makes Ji Xihe's heart flutter.
At last, through the psychological primacy effect, the planet closest to the sun keeps drawing nearer until the two collide and merge, turning night into day.
