Anyone know this drama name?

I saw a fan-made on YouTube, in that drama ML is a celebrity always goes around wearing a mask to avoid being recognised and.one day FL mistakes him as her friend and strangles his neck but gets shocked seeing him and her friend arrives from back. She drops her diary there which ML finds and she starts to work under him.

Does anyone know the name of the drama? I don't know if it's a kdrama or not.

Thanks in advance :)

Allow me to join you wih a question of my own.

I'm looking for a name of this k-drama, where the two main leads spend their time joining and working up to becoming a police officers. In the starting episodes they go through challenges of this "cruel" police academy (or whatever this institution name is where the future officers are being taught) instructor. I remember how the whole group of students had to run in circles (training), and how the male main lead worked out (sit-ups!) in his little apartment in his spare time or breaks between studying (for police uni exams or something of that sort).

I appreciate any help, and also wish good luck to you @Veera94.

The drama name is called Police University. Its a Korean drama starring F(x) Krystal and B1A4 Jinyoung

Hey, I should've mentioned, it's not really a new/recent drama (from '20 or '21) like the one you've kindly pointed out to. It must be a few years now that I've last watched/seen it. Thank you for your time anyway! :)

Oh my, I checked that title and didn't believe it was the one, until this moment with your gracious help, indeed confirming it as the scenes from the EP1 match the ones in my memory. Thank you very much, you just made my nights (very literally)!
