This one is real interesting! I've only read the 2 volumes that have been translated so far, but I'm pretty much hooked. It's a real intriguing premise and both the main characters (the death row inmate and the main protagonist) have very nuanced characters. So far, I am not sure you could call this a romance manga as much as it's a sort of drama/murder-mystery, but depending on how far the protagonist goes it could really go in any direction. There's a lot of motives at work between both main and side characters, and the way these motivations play off each other to drive the storyis so far very nice.

I'll be looking forward to further chapters with excitement!
