Male soldier and Nan Jin's former brother-in-law, the second son of the Gu family. He has a buzz cut, slightly tanned skin, and is noticeably taller than Gu Shaoxuan. He is the same age as Nan Jin but six months older, having always considered himself her elder brother. He was shocked to learn of her divorce and lost baby. He brought food supplies (cans, apples, biscuits) for her. He had not been home for over half a year and was unaware of family events.
