Yoshida is completely drunk out of his mind and ends up letting Sayu stay at his place overnight. The next morning, he wakes up to the delicious aroma of miso soup in his kitchen.
"Who the hell are you?! Why is there a high school girl in my house?"
"I asked if I could spend the night and you said yes."
"There's miso soup..."
"You asked me to make you miso soup yesterday."
"What?! Like I'd ever do that!"
Not having the heart to put Sayu out on the streets since she ran away from home, Yoshida allows her to stay at his place...
And so began the awkward, irritable, and slightly heartwarming relationship between a runaway high school girl and a salaryman living together.
