Help me find this BL manhua

I forgot to put it on my list and forgot the title.

The plot is when the MC had a red string attached to the ML which is a famous celebrity but on the other end of the string attached to the ML is black. The MC is a famous child actor but he got into an accident and got a scar on his face, losing his acting career. Then the MC felt like the ML replaced him. That's what I know so far.

Please help me find it
