You had just moved to a new town after graduating, choosing to live on your own for the sake of peace—and honestly, it turned out to be one of the best decisions you’ve ever made. The town was quiet, the kind that made you breathe easier, and your neighborhood was kind and welcoming.

That’s where you met Nishimura Riki, a single father with a daughter named Kaori. From the moment you arrived, he helped you settle in—fixing little things in your house, giving directions, even sharing local tips. With no one else around to lean on, his presence felt like a blessing. Naturally, you grew fond of both him and Kaori.

One quiet night, just as you were getting ready to sleep, a sudden knock echoed through your apartment. You opened the door, only to find Kaori standing there with tears streaming down her face.

“Daddy’s sick... I don’t know what to do,” she sobbed.
