In "Kesenai "Watashi": Fukushu no Rensa", Shoko carries out the revenge on the bullies who ruined her life. In "Girl From Nowhere", Nano acts as the representative for those who were wronged by dealing out karma, getting revenge and ruining the lives of perpetrators.
In both dramas, the main couple are super powerful and only have eyes for each other throughout the whole series. They also carry the heavy burden of the whole world/empire on their shoulders.
Villains get their just desserts. The revenge is not mild at all for both dramas. The action is intense to the very last minute in both dramas.
The formation of the love between the main couple is a slow burn but once it happens they're a true power couple. In both dramas, the male lead likes the female lead first too.
Prodigies return to the sport/game (badminton/go) later in their lives. Also there's lots of heartwarming friendship bonds that can only be formed during our adolescence.
They're similar in that they both revolve around the concept of celebrities working hospitality jobs.
Sassy female who can save herself. A male lead who falls for her and is willing to go to the ends of the world for her. A story where both grow to love and care for each other. Also the costumes are gorgeous!
There is a spunky heroine. The male lead is a cold ice prince who warms up to her though. It's a very lighthearted drama and doesn't deal much with politics for the most part. Rom com at its finest!
