One of the most interesting yaoi manga that I read. The beggining have that misterious air about the twins past and all, and how the omega has to deal with it as the new "pet".
From the middle to the end we stars to see "they're twins but still really different from each other, even though they do look the same" and we see how the simple fact that the omega can now differ them both can impact them a lot... LOTS of drama after that xD can't say more than this
