I read this manga in one go and I must say, tears wouldn't stop rolling down my cheeks. This hit way too close to home. Despite how tragic and miserable the story was, it's also a masterpiece in its own way as it makes us realize that things happen for a reason -- in ways that could help us better ourselves in the future. I did like the ending despite how sad it was. No other ending could have done the story any justice as this one did. Hands down, a must read!
