Review of Sing "Yesterday" for Me

How do i put this? I do enjoy watching it, but yet satisfied with the story I also have high hope throughout episodes... but it didn't meet my expectation. I've watched something like this before. and that gave me a blast. This Anime... still a question to me. Instead of having a heartbreak, this one threw my brain off. The time leap is kinda offset. i thought i could swallow it up if the ending would give me something worth in return. I don't know what other think about it. The ending is sorta crab, it makes me feel like (i wish I hadn't watched the last episode). if otherromance anime had Lvl 5 of relationship complication. This Anime is like one level below that.

As always.

Does this anime is worth to watch in free time?
-if you really! don't have something to do.you should give it a try

Is the story good?
-I bet your own imagination 'story' is better than this.

What should i do with it?
-it's not that I don't recommend to watch. The first half was good, but overall it wasn't my thing~
-your way of taste might be different. you could always drop it down if you don't feel right about it XD
