Smurfini's Things

I recently remembered this BL Manhwa but I can't find it anywhere, please help me find it!!

The top is an actor (at least someone in public eye, but most likely he is an actor). The bottom is someone who work on set. That's also how they meet. Of course the bottoms entire life gets turned around because a high profile person likes him. Two things I remember in detail, is that at some point (pretty early on I believe), the bottom gets told to go grab something or do something. So he does, but when he returns, everyone is gone. They forgot about him. Of course the top realises and goes to him. I also remember that in situations like this he has a trauma. Like being abandoned or alone in the dark or something. Then another moment I remember is that people are handing out official staff coats, but the bottom doesn't get one because there is none for him. So the top gives his to the bottom
