My Rules Weird Girlfriend

(Ghost story with rules + a small amount of Cthulhu + light suspense + yandere + single female protagonist,) "You must kiss her once a day, look at her for ten seconds every day, and say good afternoon to her every day, otherwise - you will lose a part of your body." I thought it was just a temporary job to "take care of my girlfriend" for my roommate, but I didn't expect that this kiss pulled Lin Xun into a weird world called "Rule Weird Talk". Here, the rules are not moral constraints, but a survival contract with murderous intent. Li Sheng, a strange person who appears inexplicably, what is her true purpose, and Li tide, a human who appears in the dungeon, claiming to be married to Lin Xun, who is she, and why does she look the same as Li Sheng. Dungeons are opened one after another, and every rule is a game between human nature and memory. Lin Xun was eager to find out what the truth was about Li Sheng and Li tide. Is all this protecting him or designing him? When the world of rules and reality intersect, and love and deception intersect, Lin Xun must make a choice between emotion and reason. This is not only a ghost story game, but also a test of "irresistible love". Are you willing to pay the full price for her?
