Jiang Xinglong returns with the regrets of his past life. In the past life, Xiaoyu quietly saved money to support the down-and-out him, hiding all her gentleness until her passing. In this life, he hurries forward in advance, closing the distance through tutoring and catch-up lessons, protecting her away from trouble and harassment, step by step taking the isolated Xiaoyu under his wing. The deep affection that no one knew of in the past life, in this lifetime, he wants to return in full, solely to keep that girl who pours out goodwill.
