Byeon Tae-in was an ordinary geek, completely engrossed in webtoons and internet culture—until one day, everything changed. Gates opened, monsters poured out, and humanity teetered on the edge of annihilation. But unlike everyone else, Taein didn't feel fear; he felt a rush of excitement, as if he had been thrown straight into one of his favorite webtoons! "These monsters look like the weak ones that always show up at the start to highlight the hero's new powers!" And then, something extraordinary appeared before him: [You have been chosen.] Status window? Perfect! Taein had consumed every webtoon in existence. Now, if he becomes the strongest in this world... what kind of epic story will he write next? (Source: Naver Corporation, translated)
