Watakushi to Kowareta Kyuuketsu Ki

Synopsis:

As a child, Itsuki met a mesmerizing boy who lived alone in a castle atop a distant mountain—a comforting presence during a time when her parents had left her in the care of indifferent step-siblings. But one day, he vanished without a trace. Years later, weighed down by the responsibilities her parents abandoned, Itsuki longs for someone to care for her, just as she once dreamed. Then, in a twist of fate, the boy from her past reappears—saving her from a life-threatening moment. However, something about him is different. His demeanor is distant, his actions unfamiliar. Itsuki begins to question who he really is, what secrets he’s hiding, and what it is he truly wants from her.
