I watched the anime adaptation a while ago and I decided I should read the manga to see what happened after that ending.
What I found was a dramatic story that had me crying for the last - at least - 25 chapters.
I love every character, since they are all refreshing and funny. As for the story, yes, it is a bit confusing, but I seriously recomend to continue on reading, since everything will be clarified in due time.
I don't regret reading this manga at all, I found it to be funny, dramatic and both heartbreaking and heartwarming.
