Kei and his girlfriend, Ako, share a quiet, happy life, bonded by their mutual love of astronomy books and stargazing. But one morning, as he sees Ako off, Kei takes off his glasses and runs a hand through his hair—revealing that he is, in fact, Ryo, Kei’s older twin brother, pretending to be him. A month earlier, Kei died in a tragic accident in New Zealand. Devastated and confused, Ako mistakes Ryo for Kei when he suddenly appears before her. Unable to break her fragile hope, Ryo decides to keep the truth hidden. As Ryo struggles to maintain the lie he’s living, he finds himself drawn to Ako’s warmth and sincerity. Slowly, she becomes someone he can’t imagine losing. But Ryo isn’t the only one with a secret—Ako, too, is hiding something she can’t bring herself to confess.
