anyone knows what drama is this?

saw this drama in online in insta I think
boy and girl trying to tell each other dont fall for me and try to not date each other.
The scene I remember was the boy hand the girl a paper, she opens the paper and its the bill (prob for food) and he says the amount and tells her that you know where to send it. The actor both where around 30s I think. anyone knows which drama is this?
