Ggg's manga / #vampire(4)

Short and good, but sad. The male antagonist is so tragic.

In a small pool of vampires, a 19-year-old boy named En gets turned and is the talk of the town. Main character iusi falls in love with him and vows to restart his life with the kid. En starts to really like this guy and wants to figure out their relationship, but can tell he has a complicated past. In the last moments his 'past' shows up after breaking out of the 'center' (prison) and claiming himself the mans pair.
