Wtf this is too sad and realistic
The others r saying that it's not incest so is the brother like from that story about some demon who puts their child inside a pregnant human and brings misfortune or some shit because that wouldn't make them blood related since they dont have the same mother or father it's a completely diff being lol
Wait if he can only see red than y not get some red and black paint, mix them together and u get dark red or u can get white paint to make it a light red or pink???
nah he only sees blood red and only recently started seeing pink. makes no sense but assuming he can't see dark red either.
