Single father Mo Chanyeong has been busy raising his daughter on his own.
Then one day, Ryu Seok, his first love who disappeared nine years ago after ghosting him, moves in next door.
Chanyeong finds himself increasingly bothered by Seok, who has become even more shameless and promiscuous than before.
To make things worse, he discovers that Seok is actually “Yoon Soo,” the writer he has always admired.
As if that weren’t enough, Seok casually brings up their past relationship and even provocatively asks Chanyeong to “help with his writing” using his body…
“I liked it best when I was with you.”
