Osananajimi wa BL Suki na Kyuuketsuki

Souta's childhood friend Nene was always a fujoshi,
but recently she's also become an immortal!
A vampire bit her at the convenience store.
Since she likes staying up all night playing BL games anyway
her life as a fledgling bloodsucker isn't so different.
But now she's doomed to repeat the same year of school.
She'll never age. She'll never die. That's bad.

Can Souta restore Nene's humanity?
He searches for the one who turned her in the night street...
