First thing for those who watched the anime before: Novel story is completely different from the anime. Rikka and Yuuta are a pair of chuuni and ex-chuuni. Some background stories about them are different but some are same. Story: The story took us to Yuuta's school life and how he got involved with Rikka through daily encounters. The story is in Yuuta's first person POV focused on how they met, interact every day in school, and finally became a lover. The story is quite straightforward without many sudden plot twists. Art: Sadly, there are very few illustrations so it quite hard to grasp the story visually. It's up to yourimagination how they are doing things. But the splash images isn't disappointing at all.

Character:
We can see in Yuuta's POV how he doing every day and how he feel about every encounters. Character developments aren't drastic ones, as there are no very eventful conflics.
The main attraction of the characters I guess if from how the people interact with a chuunibyou girl who see the world from a different perspective and how cute she is.

Enjoyment:
I found it very enjoyable because it's very relatable. It just like we experience how we met and fell in love with someone, in this case a chuuni girl.
We'll see how a pair of chuuni found each other, involved with each other, fell to each other, how they spend time as a couple with their own way, and how they resolve their problems as a couple.
