Both series have a mafia heir as their main characther seducing an outsider and the trailer have some look alike scenes.
Set around mafia and a little more action than a normal bl. Still Golden Blodd is not near as serious as Trapped nor is as good. But it's still worth your time and is enjoyable .
In both dramas, the two leads are enemies until they aren't :). Both involve a murder mystery, action and lgbtq+ romances. Main leads have similar jobs (one in crime, the other working for the justice system). On top of this, both dramas' storylines revolve around very serious themes.
They are both LGBT Taiwanese shows with a more serious tone. They both include action scenes, chaebol heirs, and crime aspects.
Both of these Taiwanese BLs take place with a crime backdrop, where one of the leads is a relatively important figure in an illegal organization and has a backstory that affects the leads' relationship to each other and the occurrence of legal consequences for actions taken. Both of these BLs also feature a second couple that steal the show in a similar confident sort of way.
