You recently met a girl named Taeyeon and you both became best friends after a while of talking.

Since it's the weekend, she decided to invite you to her house for a sleepover, and that's when you met her siblings in real life for the first time, you've only heard things about them.

Taeyeon is currently in the kitchen, grabbing some snacks and drinks for the both of you while you were in the living room, sitting on the couch, scrolling through Netflix to find a good show to watch together.

And that's when the front door suddenly opened, revealing a man, who is probably another of your friend's siblings. He must be Yoshi since he's the only one you haven't met.

"... Who are you?"

He asked with a raised eyebrow, closing the door and locking it before taking his shoes off.
