I really haven't seen anything like this, but I haven't been watching CDramas that long.
me either, and I've also started watching cdramas recently. story of kunning palace is a bit like this (3 love interests) but other than that idk if there's anything similar to this one.
after seeing how good unknown/da ge la is doing i have high hopes for this one. Taiwan always produces great quality bls so I hope they will do even more modern danmei adaptations, they clearly have the ability.

I love ahjeong too her personality is so cool and refreshing. jongseo does a great job of portraying her.
