Because we're already in episode 5 and there's no significant improvement to the animation, I'll keep it short, as it's still as stiff as the first episode. But the moments between Yoi and Kohaku are really cute, both the library scene and when they accidentally meet each other. I like how despite her doubt and nervousness with herself, Yoi always reacting positively to Kohaku's advancement, which makes us feel like they are budding in love. But I was shock that they introduce another character this late, as Yamamori-sensei's Hirunaka no Ryuusei, we got introduced to the second lead from the get-go.
