Shunrai to Koiwazurai

Hana Hoshino is an 18-year-old girl who has developed feelings for Sakurai, a 33-year-old man who has been her caretaker since she was 14. He has taken on the role of looking after her in place of her parents, and the two have experienced life together through various emotions and events. Hana wishes for him to view her as a woman rather than just his charge, hoping to move beyond their guardian-young lady dynamic. On her 18th birthday, she makes a bold move by proposing to him, but the situation is complicated by their 15-year age difference and the unusual nature of their relationship. They live together, and the story explores the challenges between two individuals with differing perspectives.
