This series is so cute and FLUFFY, and the ship is absolutely adorable. The plot is very fun, and I loved each and every episode of it.
The sex scene was very unexpected from a Japanese BL, and was executed exceptionally! The character dynamics and development is also very good (we love you Masayan <3).

There were many unnecessary lines, in the sense that they often pointed out things that were obvious, or had already been resolved in the previous lines. Many lines also ruined the mood of the scene, and could easily be solved with body language. There were also a tad too many flashbacks and repeated scenes. Some scenes were shown up to five times throughout the series, which is just unnecessary.
