I've reread Betsukiss a few times because it's a cute and funny vampire-human story with captivating art style (intimate scenes make your heart flutter and fun scenes make you laugh). The tsundere and idiot protagonists have an adorable dynamic along with the other characters whom have unique backstories and tie into the vampire lore (without being excessive, just enough to make you think "oh right they're vampires"). I am a huge closeted fan of yuri manga and I'd rank this high up on my list despite it only having 10 chapters and being incomplete (I read this years ago but, finally leaving a review now, soI can assure you it has a memorable storyline)

Sadly, the author hasn't updated, but I'd still read it because it'll make your day!
