Very simply put: J-Dorama at its best!!! Bittersweet, romantic slice-of-life, pure minimalistic poetry...just like a well-written haiku. It may not be the most original plot ever, but...who cares? It works like a clockwork and that's what matters! And - something that doesn't happen too often - it has a perfect cast: every single actor/actress is simply perfect for his/her role. Particular congrats to the leads, Tsumabuki & Shibasaki, but also the supporting cast did just great! Well-deserved 10/10!
