The Killer Who Never Kills (2011)

Quiet youth Ouyang Feng is an apprentice to an aged hitman who practically raised him from childhood. Feng is expected to take over his mentor's place and is given his first assignment by the obnoxious boss of his organisation. Ouyang takes the approach of getting to know his target so that any hit can be made to look like a perfect accident. However it also means he begins to sympathise with his first target - a geeky cosplay fan targeted simply for 'lying' to the big boss during an altercation. Deciding to fake the victim's death and pretend that the job went to plan, Ouyang finds himself repeating the feat with his following assignments and assembles a trusty team that helps him pull off the trick. A few unexpected twists threaten to derail their efforts and reveal Ouyang to be a killer who never kills.
