Doona!

“Sh**ting Stars” is a rom-com about the people who work behind the scenes in the entertainment industry, Despite the hurdles of dating a celebrity, the couple never once break up and stay devoted to each other the entire time: they only have eyes for one another! In addition to the delightful romance, it was wonderful seeing all the work that goes into the industry as Starforce Entertainment does their best to manage their stars. The friendship and bond they have as a team were definitely highlights of the show!

After a terrible first encounter between the two, Geun Young gets fired from her job, and believing that Who Joon is the cause of this, Geun Young becomes his anti-fan. A variety show producer then comes up with the brilliant(?) idea to cast these enemies on a virtual marriage program, and naturally, their plans to make each other’s lives difficult don’t really go as planned. For those like me who love light rom-coms and K-drama cliches, “So I Married the Anti-Fan” is a must-watch.

It has the same story of former idol characters/character.
Totally different storyline and genre but have the basic "idol" in them.

the story revolves aorund the kpop idol and his childhood crush who lives next door , Both these are similar in Celebrities fall in love with commoners
