One month ’till Christmas Day. Students at Shigure High School are excited about it. Toru is also looking forward to it. But there is one thing that worries him: a girl who appears in his dreams.

## Characters
### Hirose Tooru (広瀬 徹)
Several years ago, he lost his parents in a car accident while on a trip.
Since then, he has lived with his sister and grandparents in a landlord's house.

Tooru was an ace member of the archery club, but since his parents passed away, he has not been active in the club since he and his sister have been occupied with their own lives. 

To earn money for himself and his sister, he works part-time at a coffee shop owned by a woman close to their mother before her death.

### Hirose Yui (広瀬 優衣)
Toru's younger sister. She was separated from her parents in a car accident during a family vacation. Since her parents are no longer around, she moved in with her brother and now lives with him while attending Shigure Academy.

She has a caring personality, perhaps out of concern for her brother, who earns his living expenses independently.
Because she lives with her brother and has to take care of the housework, she does not belong to any clubs nor has a part-time job.

Yui is an earnest person but sometimes does silly things. She is a serious brocon and secretly keeps items related to Toru (such as Toru's unused clothes and his baby teeth). Furthermore, she keeps a diary about her brother's daily activities.
