HIStory3: Trapped (2019)

History3: Trap and Advance Bravely have a very similar vibe. Trap is pretty much the gay version of Advance Bravely.

•Involvement with bad guys
•Innocent loveable ML
•Brother-sister relationship
•Orphan/Adopted ML

This was the first BL drama I watched and really liked a few years ago. I know KeiXYaku is not romance genre like trapped and focus almost completely on investigation part but the similarity between Police and Gangster working behind the back for the mysterious death of someone’s close to them is undeniable.

Whilst these are two completely different genres - they both feature a gay romance plot.
Trapped is a series rather than a short film and tells the story of a mob boss and a cop who fall in love - it is Taiwanese.
