looking for a yaoi

i'm trying to find a yaoi, but i cant remember the title. its about a kid with a clover birthmark of his hand. he was abandoned as a child in a box and was found in the river. since then he always looks in empty boxes to check if anything is in them. on time he almost gets hit by a train. i think he wants to be an actor and he meets his idol who once saved him from drowning....
