And the scene you describing is like one scene from chap. 36 on this manhwa
Guys help me out. So like its a webtoon? Where theres one guy (j think he had black hair) and theres this other guy (i think he had red hair) and they are like stuck in this house and the red hair multiplies. And thats all i remember (sorry if it doesn’t make sense )
