On a warm, cloudy afternoon, Tomari bursts in on two girls from her class, Hazumu and Yasuna, sharing a tender first kiss. Her heart breaks... from jealousy. Hazumu was born a boy, but he certainly doesn't act it. He's sensitive, delicate, and loves gardening. Lucky for him, he grew up with the tomboy Tomari, who was always there to protect him. Despite her own feelings, she pushes Hazumu to confess his love to the elegant Yasuna. After Yasuna rejects him, he retreats into the mountains in despair. This begins the strange series of events that changes him into a her, and earns her the love of both Yasuna and Tomari.
