Help finding Kdrama

I watched my first kdrama like 4 years ago but can’t remember the name for the life of me. I watched it on Netflix but don’t know if it’ll still be on there now. All I can remember about it is: -the FL was in like an arranged marriage thing because of her rich father? And ran off in her wedding dress right before the wedding started. -The ML was an idol who FL had never heard of before. -They met when ML was running away from either fans or his manager and he hid his face from them by pinning FL against a wall and pretending to kiss her.
