Is it a completely different person from the brother who happens to look the same or the brother with memory loss? I don't have a the patience to check if they mentioned his name ╮( ̄▽ ̄)╭
Yes! And there was one panel where Shin was looking at them a little chocked and Jake called his name and then he got into the sex again, I wonder what that was about ….
Really curious how'll our kitty cat solve this problem
