Hirono Hiro is a student and a mangaka. On Christmas Eve, fate brings him to meet a girl named Miyamura Miyako. They become friends, and eventually like each other.

Shindou Kei is Hiro's childhood friend who always calls him "onii-chan". As you may predicted, she also likes Hiro.

Tsutsumi Kyousuke is a member of movie club and a dedicated cameraman. One day he accidentally captures a beautiful girl in his camera, and decides to find out who the girl is.

And guess what, the girl is Shindou Kei. So it's up to you to call it love triangle or love square =P

Shindou Chihiro is Kei's twin sister. Chihiro got in an accident few years ago and has memory problem. Her memory disappears after 13 hours. Therefore she maintains a diary to remember every little things happened in her life. The diary book is her memory, her life.

Asou Renji is an ordinary student from the same school as Hiro and Kei. He met Chihiro at an abandoned train station.

One anime, two storylines. Twin sisters, different stories. Recommended for 13+. My rating : excellent.

Why am I standing alone in the twilight
Let me go, no more lonely nights
I take a deep breath under the hazy sky
Feel like losing, but it's gonna be alright

Break through the night, go and try to fight
Don't be afraid, now is the time

Be alive, take it
I surely feel my heartbeat
There's no limit to my reach
I say good-bye to my tears that I don't need
So believe in my dream

Don't look back to the sorrow I left behind
Here's my real intention I hide
I wish you were here, and so just right by my side
Need to be strong enough to swallow my pride

I have been looking for my own style
Don't give it up, here comes the life

Be alive, take it
I have learned a great deal
Brighten our sweet memories
Hope there will be a future for you and me
So believe in your dream

Be alive, take it
Promise to find, yes I will
Shining wings filled with wishes
Fly high, make it
Get to the new world that I seek
Someday, so I believe
