The Heart Killers

They both include main characters hiding secrets from each other. The brothers in The Heart Killers are assassins for their "mom" while Kinn and his brothers are part of a mafia family that regularly kills people to get what they need. KinnPorsche has morally grey characters like VegasPete, which are similar to KantBison in The Heart Killers (in the beginning).

The themes and the tone of KinnPorsche are much darker than The Heart Killers but I do think if you like one you'll like the other.

JoongDunk the actors star in both BL dramas which have crime and killers in both. There is deception and uncovering of secrets as the drama progresses. Joong is the serious character and Dunk is the playful character in The Heart Killers and their roles are reversed in Dare You to Death.

Similar elements of danger with unlikely romance woven in. Both stories have a promise of dangerous plots, but end up not being that dark.

Just ur taste if u liked heart killers. it is sensual with a good storyline.Moonlight Chicken is about two romances that take place for the workers at a chicken rice restaurant and the lives of their employees.A delicate script, with some forgivable flaws, endearing characters, excellent cinematography, and incredible performances.

Both The Heart Killers and Long Time No See are centered around a hitman based storyline that also includes BL or Gay Romance.

The Heart Killers is a Thai series.
Long Time No See is a South Korean film.

Both are Thai BL Drama Series that have a gangster vibe to them. In The Heart Killers, it is about a pair of hitmen brothers and a police spy and his mechanic friend. In Jack & Joker, it is about an ex-convict / thief and an enforcer for the mafia.

Both are Thai BL dramas that are action/crime themed with an enemies to lovers plotline. The Heart Killers has more rom-com elements while The Wicked Game is expected to be darker and more serious.

- action BL
- from enemy to lovers trope
- the one of main lead is a criminal person
- clingy main lead
- spy-ing kinda story
- old money kinda style ( the series feels like in old times or have 1990s vibes )

Both have main leads who are dominant, both have some violent themes/complex characters. Both have main leads who are addicted to the second lead despite the danger/trust issues or morals surrounding the relationship.
