Chapter 1-3: Aihara and Maki's story
I couldn't stop reading and I really thought there was more of them. I liked them both, really. Such entertaining characters. I liked that Aihara was, truly, a gentleman, and not some hormone-driven sex-machine as is usually the matter; Maki too was a compelling uke, very true to himself no matter the circumstance (yes, even at the very beginning) and I loved that he wasn't a wuss. Because he feels pressured easily and he has a very low self-esteem, it follows naturally that he can't value himself favourably and he ends up misjudging his own strength. In more than one occasion though we get to see him fight. Good for you Maki, I love you. Fufufu. Overall, it was quite a satisfying read. The only downside was the third-wheel, the cousin: did not see his point, did not like his personality. Why are the side characters so damn predicable with Yamamoto-sensei?
Chapter 4 (Mirai and Gaku) and Chapter 5 (Us, Blooming) were too short for me to say anything specific. Be it as it may, out of the two, I liked Chapter 4 better. The characters were much more interesting and unique, if underdeveloped, and this was the plot which called for a sequel, not the one with the flower shop. In chapter 5, although I liked Haru and Ryou, Takashi was too flat and boring, not deserving of the lead. I won't be reading the sequel, that's certain.
Overall a very nice read, especially for the main story and the art which gets better and better.
