One Fine Week (2019)

The man is a famous star. The woman is a star, which career is facing trouble. She does sneaky and desperate things to try to make herself more popular..
His fans and the rumors of the relationship with her could ruin his career.
Somewhere in the middle another guy starts chasing her...
She is/was in female idol group and although most of the other members are her friends.. another one is her greatest enemy.

Both dramas have 2 girls with identical faces, but totally different personalities. Because one of them is in great trouble.. in a moment important for her career- the other one switches places with her. While playing that role - she falls in love.., but has to continue pretending.. to be the person she isn't..

This drama is s 1 of One fine week.
You should watch 1 before watching 2
- Same male LEAD and female LEAD.
- twins switch

Both one fine week 1 and 2 and SIMAAF involve a relationship between an idol and non idol, meeting through and forming a relationship through a reality tv

Identity swapping all the way around. How would it feel to exchange roles with a person's life who is completely different from yours?? From trying out the foods you hate to learning to be a woman , you have to survive a week as someone else. Season 2 is also up!!! Go watch it;-)

Both webdramas are about the kpop universe but also talks about the k-entertainment world and how sneaky it can be. The two main female leads have doppelgangers and switch positions.

Both k-dramas:
-Are acted by popular k-idols.
-Highlights topics of the Kpop industry within young idols.
-Revolves around music (songs, choreographies, performances).
-Speaks on idol scandals, favouritism, saesang fans and secret relationships.

also pls don't copy my words. If you need help with writing just message me!

The only thing that is similar is that both these dramas are about idols. So if you're wanting to watch more dramas (or webdramas) involvinhg idols, i recommended top management :)

Nothing is much similar to it. Just want to recommend another good web drama that everyone need to watch
Both dramas are kinda refreshing and for youths. It's the drama that can't dissapoint anyone
