Both involve a "cold" woman saving a childfrom abuse and portrait the deep connection between childless woman and traumatized child

Mars is one of my all time favourites. Bad boy x Good girl trope. Motorsicles play a big role and the mothers of the female protoganists wont win best parent anytime soon. Epic romance feel.

Both follow the bad boy x good girl trope and involve gangs. They also have some melodrama in it and problems with a missing parent figure. Epic romance feeling.

In both dramas the hero likes the heroine first and in both their struggle to win her over is really entertaining to watch. They're also workplace dramas and have a similar feel
