Sayu is from the game "Genshin Impact". Standing at a petite and delicate stature, Sayu's lack of growth compared to her peers deeply concerns her, leading to an obsession with growing taller. She firmly believes that ample sleep is the key to achieving this goal, going to great lengths to create opportunities for extra rest. Day by day, the world seems to be sprouting skyward, and only she remains small as ever. Growing taller has gradually become an obsession in Sayu's mind.
