Review of Sing "Yesterday" for Me

The first two or three episodes, i think "hey, this looks so good, and Haru is strange but really nice", and i've think that about Haru until the end, but not about the rest of the anime. The protagonist and the woman he liked, they both are very stressful, but much more the woman. The protagonist is a loser, no much more than this, he doesn't realize what he has, and what he deserves, but about the girl ... i'ts, agh, repugnant, she is so confused and inmature, even if is not her intention, she play with the heart of the loser protagonist and otherboy. And that last thing, is really really... really annoying like to see Haru sad about the protagonist. In summary, is a good anime with characters so stressful, exception Haru, she is the best of the anime, and the only reason why i rate this like "good".
