Orange Days
Well, I just finished this series a few minutes ago, and it's so good! It leaves you with that bittersweet feeling you get when you finish a good series or book. Orange Days is sad and cute and funny and happy and endearing and uplifting and all that good, mushy crap that a drama should be. The acting is good, the main characters have great chemistry, plus it has Hiroki Narimiya in it! <3 Highly recommended, you guys should definitely check it out. In case you wanna know more about it:

Kai Yuuki (Satoshi Tsumabuki) is in his senior year at university studying social welfare psychology. At present, he is in the middle of job-hunting season. He is finding it difficult with no job offers so far.
One day, he meets a girl who is playing violin in the campus. She is Sae Hagio (Kou Shibasaki). In marked contrast to her beautiful tone and attractive looks, her personality is somewhat impertinent. And to top it off, she communicates through very vulgar sign language.
Four years ago, she lost the most important thing for a violinist - her hearing. As a result Sae closed off her inner self from the outside world.
Kai finds himself on a date with Sae, in place of his best friend. Unexpectedly, he comes into contact with Sae's private side.
Love, job-hunting, friendship... Setting a campus in spring as a dorama`s backdrop, it's the start of a glittering youth drama.
