Help me find this actor/showbiz manhwa pls

I don't remember much but I do remember this one scene :

The mc has to act like a suicidal man, jumping off a building. The film director was wondering what the mc would do, take off his shoes and hesitate, look at the sky and cry ?

In the end, the mc didn't take off his shoes(I think) and jumped off the building with a huge smile on. (The mc was actually very depressed even outside his given role) The film director was impressed by his acting bla bla bla
