Not a harem, they're talking about the side story where the author had it in the last 5 chapters of a more "what if" and I think he picks one [don't hold me to that last bit]. The author wanted to keep it purely story all the way through and did the side story more so for the fun of it. No worries!
I've seen alot of people saying that this manhwa has a harem into it. Bro seriously, this one too? I would've enjoyed it more without those girls fr ☠☠
