I went into this half-heartedly, and I came out of it smiling and truly satisfied. This was cute, and I'm glad I stuck with it in the end. It was refreshing and always interesting to see any sort of change on Kuzumi's face. The ending couldn't have been better for each of the characters, as [spoilers] everyone got together in the end lmao. Did indeed get annoyed at some of the characters and the misunderstandings, and how Kuzumi wouldn't say things even when it would have been good, but I get that it's all for character plot.
I have to say my favorite character had to have been Haruna, just because he was adorable, gentlemanly, and a seriously good friend.
Kusumi-kun, Kuuki Yometemasu ka?
