Yoo Jian, codenamed [Sev], is an S-class agent for the top-secret, government-affiliated assassin organization, “Rest.” After becoming the youngest agent to successfully complete 300 assignments, he finally reaches his long-awaited retirement.

Jian can now finally put into action the modest “healing bucket list” he has been planning for 20 years.

His first bucket list goal for retirement: [Earn money legitimately without killing anyone.]

“Boss, I am ready to be deployed to the convenience store immediately. I’m the kind of person who always completes his assigned missions.”

However, contrary to his desire to fulfill this perfectly ordinary dream and live a quiet life, unpredictable incidents and a suspicious woman keep crossing his path.

An assassin’s second life, fraught with hardships and adversity.
Will S-class killer Yoo Jian be able to achieve ordinary happiness without getting his hands dirty?
