These chapters don't actually belong here. They're already in their own separate story: http://www.mangago.zone/read-manga/aka_to_kuro_katsura_komachi/
Hopefully, they'll get them removed quickly to reduce confusion and further mistaken uploads. Rouge is getting a second volume about the main pair and it will mess things up if people keep adding the Aka to Kuro stuff here.
yes but it is already related though right like spin off, not much of a problem for me ^^
It will be a problem for all of us if it messes up Rouge updates
^^^^
This. They're separate mangas. They should be kept separate.
i like challenge so it is better than the first story
