Plugged In: I got Isekai'd into a Sexbot (Now I Must Save The World) - Chapter 21: Of oil-baths and an old women.

The year was 2026, and the world wasn't what it used to be. Ever since the Abyss Gates cracked open three years ago, spilling monsters and dungeons across the planet, life had turned into a chaotic mess. Cities were half-ruined, half-rebuilt, and people clung to whatever normalcy they could find. Hunters—those brave or crazy enough to fight the monsters—became the new heroes. Everyone else? Well, they just tried to survive.Fin wasn't a Hunter. He wasn't a hero either.He was just… Fin. A lanky 19-year-old with messy brown hair, a chipped front tooth from a dumb skateboard accident, and a power that everyone called useless. Absorption. Sounds cool, right? Like he could suck up energy or steal someone's strength. Nope. All it did was let him “feel” things he touched a little more than normal. He could tell you the exact texture of a brick wall or how warm a coffee mug was—big whoop. No fireballs, no super strength, no flashy moves. Just a glorified touchy-feely trick.“Fin, you gonna eat that sandwich or just stare at it like it's gonna confess its life story?” Meg's voice snapped him out of his thoughts.He blinked and looked across the rickety table at his best friend. Meg was short, loud, and had a wild mop of dyed purple hair that she swore made her look “intimidating.” It didn't.

At the age of 15, He Jin found himself a “husband” in an online game, their love was filled with loving affection and sweetness. However, because his study was being interfered with, his parent cut off the internet, he didn’t even have a chance to say goodbye and had to disappear from the game.

8 years later, the online game in the past was about to come out with a revised edition and turned into a virtual reality game. He Jin decided to login again and unexpectedly discovered that his “husband” had become a powerful player and ranked number one in the whole server, moreover, he had not divorced him!

However, the husband that was abandoned by He Jin for eight years, his initial impression of him was that of a pure boy, but now he seemed to somehow have become…….a little evil?
