Yea it's an isekai (Kim rok soo transmigrated into the novel series he was reading after falling asleep) but in no way is it BL. There is bromance here and there, along with sworn brotherhood, but the novel has zero romance and is pretty much found family at its core hehe.
Adding in a love interest would actually be incredibly ooc for Cale and there isn't actually much room to have that kind of narrative, but ngl he does develop really great relationships with other characters that it's easy to make fan ships.
Is this an Isekai or BL? But I ain't complaining.
