Gakeppuchi no Eri (2010)

Really amazing. It's really funny and heart-warming. It looks like a dorama that will make you laugh every single moment, and it does, but in the end you'll be crying like a little baby. The history is amazing, and some parts are really imaginable, but the ending it's absolutly unexpected. The acting of some characters can be better, but it's not bad at all.
Worth watching.
