I know that some people do not like Sakura Trick, because they find that the story is flat and that the manga or the anime contain only fan service but, I do not agree with that. At adolescence, we seek ourselves, we try to discover who we are and what we want to do in life. It's a big time of introspection. For some people like Haruka and Yuu, this may be a difficult step, for others it may be easier. If the story had happened more quickly, I think the manga would have lost its value. For me, the highlight of this manga is the way it shows adolescence. The protagonists do not only question their relationship, but their life in general. I also like the fact that the school welcomes its last students because it focuses on the passing of time. (Same with students of different ages) It helps us to realize that things are changing and sometimes things are ending up.
I can't say anything, because it's just kissing. Everything's kissing. A wall? They kiss on it. A balcony? They kiss on it? They also swing themselves from said balcony by flipping each other to another balcony in a strange gravity defying stunt. I'm not even kidding.
