Professional killer Joo Tae-Man has never been good with showing emotion, from his first kiss to his first time, he's been cold to any romantic interest he's had. Actor Kang Da Hyuk is one of Korea's favourite actors, known for his romantic movie roles, but wants to go into different genre's, pacifically Noir Thriller, but can't seem to pull it off.
When the two meet by chance at the convenience store where Joo works his side job, Kang believes he's found the perfect inspiration for the Noir Thriller genre, while Joo falls completely in love with him.
When the Killer Falls in Love is written by Eresemo.
When the Killer Falls in Love provides examples of:
- Distracted by the Sexy: After the first encounter, Joo becomes a blushing mess every time he see's Kang, barely keeping himself composted while near him.
- Hair of Gold, Heart of Gold: Kang
- Nice to the Waiter: Partly why Joo falls for Kang.
- The Ludovico Technique: Worrying that falling in love with Kang Da Hyuk will dull his abilities as a hitman, Joo has his friend and a fellow hitman Kim Seol-Ho (who even makes a reference to Clockwork Orange) to do this to him, so he'll stop having feelings for Kang. This treatment involves, putting Joo in a bathtube full of ice while chained and hitting him repeatedly, while playing Kang's movies on a tv and showing him pictures of him. Then when this is all done, they put a picture of Kang on a dartboard and give Joo a bunch of darts to throw at it. He then, with no emotion on his faces, hits all the darts at the board... avoiding the photo all together and creating a heart shape around it on the dart board.
- Typecasting: Kang Da Hyuk has been playing romantic leads all his life, even when he was in school, and is desperate to work in a Noir but can't seem to pull it off. This is shown when he is filming a scene for a noir movie where he's suppose to be confrontational, but instead he ends up making the other actor blush.
- What Beautiful Eyes!: Kang has very striking eyes, which is one of the reasons he's done so well in romance movies. It's also what makes Joo and other people attracted to him.
