In order to save his cold family in the future, Jiang Yu traveled back to his parents' high school days and determined to become the strongest "love security guard."
He tried his best to bring together his father Jiang Moshu, who is a straight man, and his mother Lin Shiyin, who is an academic tycoon in literature and arts. However, he did not expect that every move he made would be seen by his father's roommate Gu Yan, the flower of the mountain.
When Jiang Yu was still creating chance encounters for his parents, Gu Yan had silently paved all the roads for him, and blocked him in a corner when he "retired after his success":
"You've finished writing their script, now it's time to act in ours."
Intention: Two-way rescue
