18-year-old part-timer Yuri works at a convenience store. Serious and childlike in nature, she rarely has chances to date, so her first confession leaves her heart pounding with nervous excitement. One day, a man who fell for her at first sight starts visiting her store repeatedly, driven solely by his desire to see her, and finally succeeds in confessing his feelings. He takes the flustered girl on a date, and as they go for a drive, visit a museum, share dinner, and walk along the beach, their time together grows increasingly affectionate. Gazing into each other's eyes by the sea, they share a kiss, then silently head to a hotel where she experiences sex for the first time. A pure and tender love story unfolds.
