This whole doujinshi pretty much talks about how Remus and Sirius felt about each other. The first story is told in Lupin's point of view about how he felt when he found out that Sirius escaped from Azkaban. The second story is told in Black's point of view about how he felt for Lupin while they're living together with Lupin transforimng in every full moon. Both are pretty serious and agsty, but none the less good. Of course, the pairing would most definetly be Sirius x Remus.
