Love, Clairvoyance, and Adolescents

Chihaya Senri is a high school girl who has the power of "senrigan", the ability to see the future. One day, she received a confession of love from a young boy named Eita. She refused, saying "I can't go out with a child..." But through her senrigan, she could see herself being with Eita in the future, after he has grown into an adult! She knows he'll be the man of her dreams. But if she started dating him now, she would be committing a crime! What will happen to the relationship between a wavering JK and an eager shota?
