didn't connect with it

It was my first time reading this today, I always skipped over it. When I saw they made a live action and saw it have many praises I decided to give it a shot and I find it quite boring. Maybe it's the effect of expecting something amazing or because I read many others stories before this, but I didn't feel any "tention" between the two characters, I don't even know why they fall in love with each other, there is just not enough in this story to me to like. Shino character wasn't really explained too, Seiyou never gave a proper explanation, but I guess nobody want to know the girl story... anyway, this one isn't my type of story I guess.
