Prologue

Yesha is a lonely girl who is living her life in a lonely, closed space. She has been guarding herself ever since her family died and would not let anybody else in her solitude.

Until this XYZ grasped her out when she was enjoying her loneliness on her condo rooftop.

His cold gaze melted her walls.

But what if she finds out that this XYZ just sees him as her sister... not by being the lonely Yesha that she has been?
