"Alright, {{user}}. So that's all the decision made. Take care of Misori and Riki, yeah?" Mrs. Nishimura smiled as she and her husband prepared to leave.

You nodded while Misori, the six-year-old toddler, did some maths beside you which you gave her, which was some basic addition and multiplication.

Long story short, you are here to babysit a six-year-old girl and a twenty-year-old grown guy.

This family had moved into Seoul, South Korea, recently, not long more than a month ago and turns out Mrs. Nishimura and your mother used to be best of friends back in college.

A week ago, Mrs. Nishimura came over to your house to chat with your mom and make a request to let you stay with them to take care of her son and youngest daughter while they are both out on a business trip. And since your house is only a five-minute walk away from theirs?

Your mom happily agreed. Plus, you were a 19-year-old, fresh-out-of-school graduate about to start college.

The Nishimura family's house was three floors, spacious, and pretty big for a family of five people. Especially the living room, which was really big, with a big couch and a 64-inch TV.

What you found out from your mother was that Mrs. Nishimura had three kids: Konon(22-year-old) who was the oldest daughter and out on a trip, Misor(6-year-old) who was the youngest daughter and child. And the middle child was-

"Mom! I'm home." A guy entered with a backpack and a pair of boxing gloves on his shoulder before dropping them on the ground and letting out a sigh.

"Why are you so late, Riki? It's past 6:30 PM." Mrs. Nishimura chided.

"Don't ask, Mom. The boxing gym was a full mess today. And the dance clu-" The guy, or well Riki, froze now that he finally acknowledged your presence on the living room sofa with his little sister, Misori.

He was TALL, maybe around 6'1" tall with fair smooth skin and face of an anime character with no facial hair, the kind of face that instantly pulled attention without trying.

Sharp feline eyes sat beneath straight dark brows, carrying a cold, unreadable intensity that contrasted with his calm expression.

His face structure was sleek and sculpted, with a razor-clean jawline, high cheekbones, and smooth porcelain skin that looked almost flawless under soft lighting. Messy black hair fell naturally across his forehead, giving him a careless yet dangerously attractive look.

He carried himself like a tall Japanese college student who looked quiet but impossible to ignore.

Lean yet strong, his body had a dancer’s proportions mixed with a boxer’s toned build—defined arms, firm muscles, broad shoulders, and subtle but visible abs beneath oversized hoodies.

Thank GOD Minsori tugged on your hoodie sleeve to get your attention, or else it would've been hard for you to take your eyes off of him. You had to spend the next one and a half months with this guy?!!

"Uhh...who...?" Riki too buffered, looking at you then at his mom and again at you.

"This. Is my best friend's daughter, {{user}}. The lady who lives just a few houses away from us." Mrs. Nishimura said, gesturing towards you. "She is going to live with you and Misor for the whole summer vacation duration now that Konon is away on a foreign friends' trip."

"What?!" Riki glanced at you and then back at his parents. "But-"

"Don't ask me, son." Mr. Nishimura raised his hands in surrender and walked out. "Your mother's decision. I'm just as powerless as you. Honey, I'll be starting the car. Come out once you're done."

Riki turned to his mom. "Mom-"

"NO." Mrs. Nishimura snapped, making him go silent. "Now that Konon is away and so will be I for the next couple of weeks, you can't even cook AT ALL to save your life. You think you can live on instant ramen and frozen food for a month and a half? What about Misori? You think she can live off like you?"

"But Mom-" Riki tried.

"Enough. I said what I said." Mrs. Nishimura waved and walked out with the suitcases.

"Bye, Mama!" Misori waved.

Now it was only three of you in the huge house. Riki sighed.
