Broken-hearted and drunk, Yoshida, a 26-years old salaryman, stumbled upon a runaway-from-home high-schooler on his way back from the bar.

“Hey, you. JK.”*

“What the heck are you doing out here. Go home already.”

“Uncle, let me stay at your place for the night.”

“You can do ‘that’ to me if you let me stay.”

“If you meant that as a joke, it’s not funny.”

“I’m not joking. It’s fine by me.”

“Then allow me to tell you that I have no interest in brats.”

“Hmm?”

“Then, just let me stay.”

Notes:

[*] JK is slang for Joushikousei (high school girl)

She was once a billionaire, but she died in a car accident after being framed. She was reborn as a 21-year-old unknown actress. The previous owner of this body had been unpopular due to her vanity, two-faced behavior, and nitpicking during filming. But now, she is simply being herself, pursuing nothing but freedom. However, her ex-husband suddenly appeared. She thought their relationship had clearly ended in her previous life. She had never expected that she would become entangled with him, even after being reborn. But in fact, he had been watching her performances for a long time, since he already knew about her rebirth...
