I found it to be bittersweet. It was funny and sweet till we hear the back story of Hayato Kazunari. I enjoyed the playful banter between Kazunari and Hayato and the development between the two. I felt we got more depth and insight on Hayato than we do we Kazunari. I was shocked with the character twist on Kazunari's crush Urabe, that wasn't something I expected whole reading, but looking back you can see there was something off.
Doutei ni Ai Nante Sakebenai!
