Hum i think that the "original" is yirong bc maaaybe i think his birthname is yirong his parents suddenly had a tragic accident and he was adopted by Lin's family and changed his name. Then maybe they forced him to behave bc of his new statue and this sudden change after a brutal chock from their "maybe parents death" made him lose his mind and creating Lin who's well behaved compared to yirong and yirongs personality is maybe due to that pressure from Lin family.
Very sorry for my poor incomprehensible english I'm not native
