a lot of action scenes, murderers, seeking revenge. although kil bok soon is a movie, both contain action + darker side of crime

It's giviiiiiiiiiiiiiiiiiing The Glory tbh




because the glory is about revenge and the play a game called "Go" in the glory but in this show they play "Shogi". so many similarities so i say give it a watch because WHY NOT?!

A demon and a demon hunter fall in love. Both leads are strong and independent. The Blue Whisper has a conflict with the unjust authorities, while Moonlit Reunion is more episodic, with the leads in higher positions. Both stories are about unlikely love and are very sympathetic towards demons.

In the hope of a comeback after a scandal, an actress works for research on her new role as a secretary for a scratchy lawyer.

IDK why but they do give exactly the same vibes!!
