I loved how Koujou jumped at Yukina when she exposed her neck for him, and also how all the others (even Vatler) were like "Yeah.. we'll leave you two alone for a bit here." I guess you could say they were doing it 'vampire style'.
And seriously, how the hell do you mess up a medical check with something completely different? I guess Yukina was too blinded by love to see what was really going on. Nice to see that her own daughter is more level-headed then she is.
In all, I liked this show. Predictable for most parts, yet entertaining. And I apparently have some immunity for catch phrases, as each time Koujou and Yukina said that line, I knew shit was going down and it got me pumped up every time. Would definitely watch a second season, if there ever will be one, especially since there are still a lot of things left to cover.
