Tenshi na Osananajimi-tachi to Sugosu 10000-nichi no Hanayome Days

A man reflects on his childhood friendships with three women. Kaori, eight years his junior, is a close neighbor who declares she will marry him. Maika, a cheerful and mischievous girl he met in kindergarten, has been a constant and helpful presence through school and into adulthood. Wahana, an older woman who once helped him during a time he ran away from home, is clumsy and lacks basic life skills. She once mentioned that if he remained unmarried, she would take on a role in his future. As 1,000 days pass since their initial meeting, the man considers which of the three childhood friends will become his bride.
