春の呪い

Natsumi's younger sister Haru, who was also her closest friend, dies at nineteen, and Natsumi starts dating Tougo, the fiance Haru left behind. She sets one condition: he can only take her to places he once took Haru. Season by season they retrace those outings, and Natsumi grows closer to him while guilt over her sister keeps its grip on her. Haru's memory sits between the two of them like a curse.
