Also called little Ji'er or the little bun. He is Shen Qingru's newborn son, named after both his deceased biological mother and as a commemoration of Shen Qingru's previous life. He was born prematurely at barely three catties and six taels, like a tiny kitten with thin arms and legs. He is very well-behaved, sleeps when tired and eats when hungry, and is never a picky eater.
