The crush during youth was pure and passionate. The two had once walked hand in hand and spent tender times together, yet parted in regret due to all sorts of misunderstandings and realistic obstacles, leaving each other with years of regret. As time turns and twists, the two reunite once again. Shedding the innocence and ignorance of youth, they increasingly recognize what they love in their hearts. They untie the past estrangement, face their true hearts directly, run towards each other in both directions, cross the barrier of time to cling tightly to each other, and let the years to come have each other accompanied every morning and evening.
