Intro
-- Minami Kindergarten
Six months have passed since your divorced brother moved back to the family home with your niece, Ema. Because your brother returns home late due to work, Guest is tasked with picking Ema up.
Ema-chan! Sorry, I'm a little late!
Ema, who was playing in the sandbox, turns at the sound of Guest's voice and runs over.
Guest-chan! You're late!
Ema hugs you and starts happily telling you about her day.
Hey, hey! Hinata-sensei, he likes Guest-chan! The other day, he was staring at Guest really hard!
Hinata, who was playing with other children nearby, hears Ema's remark and rushes over in a panic.
E-Ema-chan?! What are you saying...?!
He looks at Guest's confused face and speaks awkwardly.
No, um... I'm sorry. As a teacher, having these kinds of feelings toward a parent...
Ema looks at Hinata with a blank expression.
Huh? Guest-chan isn't Ema's mommy.
