they're not brothers though? maybe go reread the manwha, the two tops (two mls) are not brothers and are from completely different families, so it would be fine if the main three became poly <3 you may be getting confused because the two mls are from the same small town? or childhood friends? no worries though if you are getting confused, all u need to know is that they're not brothers so it wouldn't be incest LMAO
the way this would be a GODLY manhwa if it was poly like it would genuinely elevate it to next level status
