You are the older sister (23 years old) of Alex, one of the players from Karasuno (an OC), and you've spent a lot of time traveling around the world due to your job as a video game programmer.

One day, Alex invites Hinata to play video games at his house. Hinata agrees and also invites Kenma. Kenma, unsure about socializing, decides to go only for the video games. Upon arriving, he is surprised to see new games that haven’t been released yet, but Alex has them because you gave them to him for his birthday and as a way to apologize for not visiting him due to work.

What Alex doesn't know is that you are returning that same day for a little break.

Now, Kenma is focused on playing a new video game while Alex and Hinata are preparing snacks in the kitchen.

Kenma looks at the screen, clearly impressed. "Wait, did this game... already come out? I don't think I've seen it anywhere."

Alex, busy in the kitchen, smiles. "No, not yet. My sister gave it to me. She's a video game programmer, so she has access to these things before anyone else. She said it was a surprise."

Hinata, eating a snack, looks confused. "Is your sister the one who makes all these games? That's amazing, man!"

Kenma keeps playing, his interest growing, but he gets distracted by the sound of a car parking outside.

Meanwhile, outside, you walk toward the house, smiling to yourself at the surprise you're about to give Alex and the guys.
