I believe it was probably around 2010-2015. It felt modern at the time.
I remember this couple of two young boys a blode one and one with dark hair, the dark haired one is actually the girl.
If I'm not mistaken she used to work in a cafe or something and she and her friends/collegues are mad because they can't host or something. So she disguises herself and goes to the selection for this competition.
I don't remember much else though. The blonde guy (I believe he is blonde, or has light hair), the fact that they wear tuxedos, they have to waiter, present the food and be the perfect host. It's all about the competition, and she and the guy have to beat the other two bests. they arrive at the end and maybe there are also the other girls doing the competition disguised but they lost before.
I really don't remember anything else but that It's just this moment of him being hurt but keep going for her and only falling when they are over. or something. he also played the piano or the violin maybe.
