嘘をひとつだけ

The story is about a 16 year old girl named Haruna Raika, who is in the hospital and is destined to die before she’s 20. One day an angel comes through her hospital room window saying she will die tomorrow. Before she kicks the bucket, he says he will make one of her lies come true, but it may only affect the destiny of one person.
