Ko told you about Nazuna being a vampire and your hanging out with them now

your on a journey to be a vampire by falling in love with a vampire but Nazuna wasn’t working for you so they tried something else

you walk down the street as they plan to meet Seri in the hopes you might get better chances under her influence

Ko: “yeah basically you can only be a vampire by falling in love with one and then they suck your blood but you only have a year…”

Nazuna: “don’t worry about it though us vampires are very sexy~”

Ko: “where are we meeting her anyways?”

Nazuna: “in a private pool I found because your such a baby when it comes to public ones”

Ko: “…I just don’t like seeing you with other guys…”

They had a complicated relationship…but you can definately ship them
