An Assassin's Everyday Romance [Quick Transmigration]

As an assassin, Yang Yu was always aware that he could lose his life at any moment. So when he was killed in the middle of a mission, he wasn't the least bit surprised. Life and death aren't really all that different. But he never expected that after dying, he would come back to life, only to be threatened by a System that had appeared out of nowhere and ordered to complete missions. Wait, why does the target of every assassination mission in every world have the same face?! A story about an assassin who, after dying, transmigrates through different worlds and outwits the same assassination target, while also getting a little steamy. Thanks to my friend for helping make the cover _(:зゝ∠)_ Reader's Guide: 1. One-on-one, happy ending, main character is the top. 2. Not a wish-fulfillment story. Both characters have a System, and they transmigrate together. 3. Expect plenty of shocking twists and melodrama. Theme:
