I refuse to be NTRED

In a dimly lit, cramped room, filled with the soft hum of multiple computer fans, Astor was slumped over his desk. Mountains of manga, figurines of his waifu collection, and half-eaten bags of chips surrounded him. His life, if you could call it that, was a continuous cycle of anime, video games, and junk food.

But even in this state of aimlessness, Astor often daydreamed of a different life. "Damn, if only I could get a do-over," he'd think to himself after a particularly bad game round or upon seeing the protagonist in one of his favorite isekai series living their best life.

One fateful night, after binging on a new series till 3 AM and surrounded by empty energy drink cans, Astor's wish was unexpectedly granted. With blurry vision, he clicked on a suspicious-looking pop-up ad that said, "Wanna start over? Click here for a new life." It sounded like the start of a visual novel he once played, but before he could even process it, his world went black.

Sunlight pierced through unfamiliar curtains. Astor... or was he still Astor? Groaning, he slowly sat up. His room was vastly different—spacious, clean, adorned with what appeared to be... medieval decorations?

Feeling strangely more athletic and less sluggish, he found his way to a mirror. Staring back at him was a younger, more handsome face with sharp features, although the eyes—those were still unmistakably Astor's.

"Dude... did I just get isekai'd?" He whispered, wide-eyed.

Suddenly, the door burst open, and a tall, formidable-looking man stepped in. "Ah, young master Kai, you're finally awake. Your training begins today!"

"Kai? Training? Bro, I just wanted to level up in my MMO, not in real life," Astor thought.
