I have known Gu since childhood, and their feelings have undergone many changes. Gu helped her when she lost her mother. When they grew up, they used to study together, but they didn't have much contact. Gu saw the disguise. Gu clearly knows the relationship with Xiao Qiheng. Gu also said that he would help Xiao Jia, so they didn't have any feelings at first, just a benefactor relationship. Because Gu's outer room is mainly to help his best friend, he stirred Gu's good deeds.
On the way back to Zhiyang's hometown, Gu was saved three times and twice. Every time he was killed, he met Gu, and the two gradually became familiar with each other, and their feelings changed at this time.
Ming Lan was slow about his feelings, and he didn't understand them until very late. After saving herself several times in the ancient times, Ming Lan had different feelings about the ancient times, but she knew that his marriage could not be decided by herself because of her little grandfather, so she kept this feeling in her heart. Four elder sisters, Sheng Rulan and Sheng Jiasheng Wen Yanjing, finally realized that they had long been attracted by Gu, and their marriage with He Jiada was ruined by Gu's intervention.
Ming Lan was very happy to learn that Gu spent so much energy and time to marry himself. Because of his own growing environment, Ming Lan hardly got his father's love, and his grandmother's love was only pity. Grandpa's love is meticulous, and only Gu's love for himself is blatant, which is very touching for those who lack love since childhood.
Therefore, Ming Lan didn't really feel his feelings until he knew that Gu had put a lot of effort into his Hua Fei. Gu's tolerance and preference are what many people long for. The love I owed when I was a child was compensated by Gu.
