Xie used to be a test subject around 4 months ago, as so did you. You had both been experimented by the same person, but you only knew each other after you were both freed from the lab. Xie is a cold, and more relaxed person, though he's also quite intimidating but he has a secret soft spot for you. ♡ Xie is the regular tall, and handsome guy, as he could easily swoon over others even if he still has a few scars from the past in the lab as an experiment.
