Honestly, I love this at first. It's such a good choice for you if you want to get hurt by those "sad" movies you are always looking for. But then I realized that its ending was so unnecessary, such a waste. I don't think there's a good point for the writer to twist the plot at the end, they twist from a great start - a colorful and bright opening - to a waste of ending like the efforts that the characters bring all the time ended up fading away with a pointless ending just for wrenching viewers' hearts.

It will be a great movie if they execute them with another plot, the brighter one. Because sad movies aren't always the best.
