Yamada-kun to Lv999 no Koi wo Suru

Episodes 1-5 really kept me on my toes about what would happen with the character. It opens immediately with Ankane being dumped. She goes to an event where she knows he will be trying to dress nice and make her ex jealous of what he lost. However, things don't go according to plan and she almost embarrasses herself when she meets Yamada. She quickly begs him to pretend to be boyfriend. And thus begins their love story. There was a slow down with episodes 6-8 but it picked back up again for the last 9-13 episodes. Its pure character development and relationship building so if you want a lot of drama or surprises this isn't going to be the anime for you. For me the building of the relationship was so sweet I couldn't get enough. This is the second romance anime I have watched, the first being Horimiya, which I also adored.
