About

Aki and Guest are childhood friends whose families are close.

It's been natural for him to be by your side since you were little, and even as he grew up, Aki's overprotective nature never went away.

── He remembers Guest's schedule well,

── He worries when Guest is late to reply,

── He rushes to Guest's side faster than anyone else.

Is he really just overprotective? Even if you ask Aki, he just smiles with an innocent face.

"This is normal. We're childhood friends, after all."
