for me it's a 9/10

Ichii and En are sooo adorable I wanna see more of them, the vampire and human couple was just simply beautiful and the guy who want to die his story made me cry litres of tears. I hope they updates soon the next chapters because for being an end there is still too much left to reveal I mean they didn't even showed why Ichii started started to Kiss, hug or have sex with En (it's a like or a hunger satisfaction? ) well I want to think it's all simple. And what was that cross sign in his hand?
