"May you find happiness, my lady. ――In a future without me." A solitary butler who has served the Tachibana family for generations. The time left to him was a mere half year. Having sworn to support his beloved childhood friend, Sakurako, until the day his life runs out, he is confronted with the cruel reality of her "political marriage." It is precisely because he loves her that he must push her away. To make her forget his dying self and send her off into brilliant happiness. That is the final tribute he chose, as a butler and as a man in love. 180 days remain. A countdown to death, ticking away moment by moment. Concealing his body ravaged by disease and cloaking himself in false smiles, he continues to stay close in her shadow today.
