There are only two characters from beginning to end, namely the male and female protagonists; a minimalist story background and the most ordinary male and female protagonists. There is no CEO, no time travel, and no scheming in this story; there is no shocking person, no sadistic love, and no deep locks in the palace wall; there is only the most ordinary him and her, and the most ordinary little sweetness between the most ordinary him and her. His most ordinary attentiveness gradually moved her, and her most ordinary liveliness affected him. How can they open their hearts to each other?
