Yukkiko can't remember a single day from the past to weeks. She wakes up in a hay bed after being hid on the head by something heavy, and can't remember who anybody is. The very thin bonds that were formed between everyone she had met over the previous two weeks are broken. Yukkiko refuses to open up to anyone this time around. She won't even say as much as a seven-word sentence. She has to open up to adjust to her new life, but can she manage doing that?
