DASS-630 A memorable hot night with my older sister, Nitei Yoru. Tachibana Mary

Kenta, who was taken in by the Tachibana family as an adopted son, had never been able to adjust to his new environment and had run away from home. Exhausted by a lonely life in Tokyo, he returned to his hometown for the first time in years, only to be greeted by the one person who had once shown him true kindness: his stepsister, Mary.

However, she was already married, and later became a widow after tragically losing her husband in an accident. As they began spending time together again, Kenta tried to fill the years they had lost, while Mary sought comfort from her loneliness, and the two gradually grew closer, drawn to each other’s warmth.
