Putting aside the development of the story, I think it's good enough. I rarely get shounen-romance that are really interesting to follow. If not shounen, mostly are seinen with their slice of life, or mature, and complex vibes.
And the weakness lies on : I agree what zeroxjac said. Next, I think the pattern is getting boring here, plus a misunderstanding between Hori and Miya is endless. Made up, fight, made up again. Just like that while showing a funny, sweet and silly side.
I prefer the development of love between the 2nd couple, Yuki and Toru. They showed a side of misunderstanding, chasing each other, hesitating.. they, still have plenty of room to develop after finally they really become lovers.
