Lin Ye, a delivery boy bound to the "Daily Good Guy System", repeats the same day every day when he opens his eyes, and is forced to perform various outrageous "rescues" on an indifferent CEO named Gu Chengyun. When he finally discovers that the other party is not only a cyclic companion, but also a villain secretly testing the world-destroying program, the rescue mission suddenly escalates - he must use the most ordinary identity and the clumsiest kindness in infinite reincarnation to disrupt a top-notch madness. This is a story about "annoying" an enemy into a savior in a cycle.
