A Bittersweet Life (2005) :–Kim Sun-woo is an enforcer and manager for a hotel owned by a cold, calculative crime boss, Kang who assigns Sun-woo to a simple errand while he is away on a business trip; to shadow his young mistress, Hee-soo, for fear that she may be cheating on him with a younger man with the mandate that he must kill them both if he discovers their affair.
Sun-woo (Lee Byung-hun) is a loyal and precise enforcer for a powerful crime boss. Trusted with critical responsibilities, he is assigned to spy on his boss’s young mistress to see if she’s having an affair. But when Sun-woo makes a personal, emotional decision instead of a professional one, it sets off a chain reaction of betrayal, violence, and self-reflection.
What follows is a gripping journey of revenge, identity, and tragic beauty, portrayed with minimal dialogue, powerful visuals, and hauntingly beautiful cinematography.
