k-drama she gets # of pharmacist to pay what she was short


Series that came out on Netflix. Maybe a year ago. Not sci-fi. Romantic drama. Woman is hanging out with her female friend eating at home at night, next day falls for pharmacist in corner store where she went and bought something over-the-counter that she'd suddenly needed & didn't have enough money so his number goes into her phone so that she can pay him back. The fact she memorized it keeps being seen as showing that she likes him. There's maybe 3 guys. I think in same show, she thinks he's following her up the stairs but really he just lives in the apartment above her floor of the building. She already has a boyfriend (with whom she dialogs as they drive places) who plays a sport like basketball on same team as other guy. They're at a dinner party at a restaurant.
