Hi, I'm looking for a BL system background danmei novel. I don't remember the title but there's 1 arc that I certainly remember. The novel may or may not be translated yet but I'm searching for its title so that I can mtl it. The arc that I remember was that the MC is the prince but he's small like a child maybe? and the ML is the regent king. The throne supposed to be the MC but the ML control it. At 1st, the ML didn't see the little prince like he hates him and he has a painting of his previous life lover but without face and he can't recall it. After the MC occupied the prince body, ML dreams about his past lover but with the face of the little prince and he hate it. Later, when he sees the little prince a.k.a the MC, he suddenly become doting. Can anyone helps?
It reminds me a bit of You Shu (There is A Beauty) arc 2, but MC is not a prince there. ML also isn't a king but the crown prince. And there is no system as well in You Shu, so maybe I'm wrong.
