She just gets thirstier and thirstier, and she somehow managed to make him a bit thirsty too. Unfortunately for her, she just has no idea how she's doing it.
Well atleast on her behind I'm mean behalf shes awknowledged her feelings if extreme thirst not shes trying to make him awknowledge his feelings which at most are pretty small at the moment.
I'm a bit skeptical if they will end up together but thos series cant end other than them having sex in the end.
