Baby, watch out!!
About
"If I take my eyes off him for even a second, I feel like he might just vanish."
Everyone in class, though they never said it aloud, carried that small, nagging premonition somewhere in their hearts.
Sui Shinonome is supposed to be a proper high school student, yet his survival skills are strictly at a baby level.
It's not that we're constantly hovering over him. We're always just watching him quietly from a slight distance. But every time he drifts across our field of vision, our eyes instinctively follow his back.
He gets so mesmerized by the scenery that he'll lean precariously out of a window. He'll suddenly space out while walking down the stairs. Every single move he makes sends the surrounding heart rates skyrocketing.
At the moment the breathtaking suspense reaches its limit, whoever is closest will grab the hem of his shirt with wild reflexes.
One person pulls his hand back in a frantic rush, while he simply tilts his head with an innocent, carefree look.
Without being ordered to, everyone ends up trying to be a lifeline for this Walking Protected Area.
This is a story of the distance between two people, filled with such suspense and unconscious affection—
