First thing first, if you're not interested in romance and drama, this manga is not for you. There's a lot of romance, a lot of drama and oh boy is it good.

For the story, it isn't to complicated Boy A likes Girl A, Girl B helps him, in some point in time Boy A starts liking more Girl B and the drama starts.
Is really simple but the execution is really good, the pace of the story is good, maybe a little rush in the final chapters, i would have liked to see more of the relationship between Utsumi and Kurokawa and maybe more development with the side characters (specially the relationship of Oonuma and Izumi) but overall is good, really good.

Now that i mention the characters, they're really good, Utsumi, is a really good MC, is not annoying like many romance anime MC and Kurukawa is really cute and intriguing, Shou made me mad, but is good because her character at some point made me mad and feel the story.
And about the secondary characters, all of them are good and really flesh out and they have their time to shine and give a conclusion to their problems, like i said i would have like to see more but overall they're all good and one more important thing,is that, they all act coherent, like a normal person of their age may act and that's something to appreciate.

There were some things in the story that i didn't like how they ended, most of it, because a person do that in real life, they would have gone to jail or getting kill or were to damn cliche, but there were little bumps in the story and are easily dismissed.
Also i have to note, that, some may say that there's a focus on tennis that is true, but is more of a plot device, you don't actually watch their tournaments, in that regard, and this are maybe spoilers, but you will see more baseball and photography than tennis.
Also a neutral point for me, the story is set in high school, so that may o may not be appealing for you.

Moving on to the art, well, is good, simply that good. Kei Sasuga really knows how to make cute girls, but sometimes, some of the boys, look weird, and somehow not really good proportionate, specially in the first chapters, but it gets better. Overall is good, not to much to talk about it.

In conclusion, i really enjoy it. It really hook me up, and wasn't unable to stop reading. I wasn't so sure that i will like it, but it really got me, it made mad, it made me sad, it made me really happy, it has some problems but they're little bumps that may be subjective.

Is a must read if you like romance and drama in general.
