Dear my Doll -~Kimi to no Yakusoku~

In a world inhabited entirely by machines, Lim and Iota make their home in a peaceful robot country. Surrounded by gentle, caring robotic maids who tend to their every need, Lim lives a life filled with warmth and affection. She is deeply in love with Iota, and her days are bathed in an endless, comforting light. For as long as she can remember, Lim has believed that these bright, sunlit moments will continue forever, unbroken by sorrow or change. However, the tranquility of her existence begins to waver when shadows from the past emerge. Long ago, Iota made a solemn promise to Lim—a vow whose true meaning now threatens to unravel everything she holds dear. As fragments of this forgotten pledge slowly surface, Lim realizes that Iota has been concealing a profound secret from her. The revelation forces her to question the very foundation of their bond, leaving her torn between the idyllic life she has always known and the hidden truth that Iota has kept locked away.
