Just need a little help finding this one, it was a super bittersweet story. Basically, there is this vampire and one day a little girl shows up demanding he look after her because she is his daughter. but at the end it turns out the vampire was actually the grandmothers lover and his photo had just been handed down in the family. Really cute, want to read it again. thanks!
Thanks everyone!! It was Amai Kamaito! And I really only remembered the bittersweet aspect where the guy mourns over all the ones he lost, the scene at the graveyard just stuck in my mind. Thank you all again!
