The light novels "# to the one who loves you deeply" and "# to everyone I love deeply" and "to everyone I love deeply" announce the decision to animate. The adapted theatrical version was released in 2022. The two books "# to the one who loves you #" and "# to every one I love" are parallel worlds and have no reading relationship. [introduction] people often change to parallel worlds with only slight differences, which has been proved in this world-the Rigao calendar, who lives with his father because of the divorce of his parents. I met my father at the Institute of Virtual Science where my father worked. The two people who have a touch of love for each other have changed greatly one day because of their parents' remarriage. Calendar, who thought he could no longer marry each other, decided to jump to a world where he would not become brother and sister. The world she's not in is meaningless.
