Just a book full of one shots if you have any requests then please let me know!

Before Yui Komori came to the Sakamaki mansion, the brothers drank the blood of each other. Mostly of Subaru's, because he is the youngest and the elders must be cared of first. Reiji makd a system for the blood sucking, because Subaru lost more and more blood lately. Of course Subaru self needed blood too, and he got that from Shuu, because he is the oldest and got the most blood of Subaru. So, it's a little pay back in Subaru's eyes. But for Shuu, it just was his duty. P.S: this will be a yaoi story. don't like?get lost. for the others, enjoy ^^

After Ayato Sakamaki leaves with Yui Komori,the Sakamaki and Mukami brothers aren't really affected but will they be affected with a sudden change in Karl Heinz's plan that nobody is aware of?
