I will brave the Fujoshi hate and deliver a more unbiased review on this anime. For the record I am not familiar with Korean anime, but have read quite a bit of their manhwa... of the BL smut variety.
I read the words 'vampire' and 'boys love' under information and was immediately intrigued. I was soon slapped in the face with disappointment. I feel that there's such a desperation for LGBTQ+ romance that the genre has become over-saturated with cliched, mediocre, immature and rather unhealthy relationship depictions. MAL describes this as erotica, its not, its smut. This anime is a cut and paste of many BL smut manhwa plots. If I'd known this going in I may have been a little less critical, after all the hentai genre is not exactly award-winning. Which begs the question: why does this anime have such a high MAL score?
Mignon is the cliché tearful abused dude, Doc is the cliché emotionally unavailable vampire dude. A reusable story unfolds. Very little actual relationship building. There is crying. There is noisy kissing and formulaic sex. The fact that Doc was a vampire was a wasted opportunity. Parts of the animation is pretty, but its obvious there was a limited budget as they rely heavily on still shots. The music was forgettable. Each episode is about 4-5 minutes, why not simply make it into a short movie? Part of me that wonders if this was a straight relationship would there have been more budget.
If you're thirsty for an animated gay sex scene just go to the last episode, if you have expectations of an actual BL vampire story carry on looking.
I think I've sh*t on this enough, 5/10
