Single for Eternity

Congratulations! You've died tragically... by dog bite. Now welcome to Aetherion a magical world where immortality is handed out like candy but only if you get married.Too bad Einar, our socially allergic, relationship-phobic MC, would rather chug poison than hold hands.Waking up in the obese body of a trash-tier noble with the personality of a rotting potato, Einar discovers he's got:1. A talking book with abandonment issues,2. A flirty system obsessed with marrying him off,3. A maid who verbally dropkicks him daily,4. And a whole town that wants him six feet under.Armed with sarcasm, a chaos-powered body, and the refusal to simp for immortality, Einar sets out to defy fate, dodge romance, and maybe just maybe become OP enough to survive the next world-ending calamity.Warning: It's not a smut, the story has dark and horror elements (Eldritch horror), MC will be single he won't elope with any woman whatsoever, MC isn't spineless or flustered kind, MC has sickening level of independence syndromeThank you
