If I truly had the chance to give her a gift, I would like to give her something special and personal. Flandre being a vampire, I would like to give her homemade chocolates that I would have prepared with some of my blood. Although I don’t know if she would think it’s a sweet idea or a creepy one. Maybe it’s considered taboo among vampires to drink a love one’s blood? I would also give her a Valentine’s Day card with a lovely message (one written by me, not a pre-written one like we see in the cards at the store). I could also give her some plushie holding a heart or something like that as I know she likes plushies. And maybe flowers too.
