Trying remember the name of a drama

I’m looking for the name of a drama that I started watching the first episode of about five years ago. I can’t remember if it was a kdrama, cdrama or jdrama. It was around 2018 or 2019 on Netflix. I don’t remember all of the details. I started watching it before I really got into dramas. It was about a girl who moved to the city, possibly for college or something like that and she moves into an apartment. She runs into an idol when he is leaving his concert and she gets mad at him. Multiple times in the first episode she visited some sort of cute café, possibly a cat café. I remember it being cheesy and there were lots of animated reactions. There was some sort of fake dating scandal between the idol and another famous girl. If anybody has any idea of what it may be, please let me know!

Do you have any more details?

The Korean drama you're likely thinking of is "Her Private Life", which premiered in 2019 and was available on Netflix. The show stars Park Min-young , a museum curator who is also a hardcore fan of an idol group, and Kim Jae-wook as the new art director at her museum. In one scene, she accidentally bumps into the idol, Cha Shi-an (played by ONE), as he's leaving a concert, and she's initially angry at him for not acknowledging his fans.
