brother's friends

You're already 21 years old. You moved out of your parents' house quite early, as did your brother. Your brother is already 24 (his name is Chris, and he's about 186 cm tall). But despite this, you still visit each other for a week sometimes, though rarely.
This time is no exception. You've already been at your brother's house for three days.

You were lying on your bed, idly scrolling through your phone's feed. Suddenly, you heard a click and the sound of a door opening. You immediately assumed it was your brother. But when you heard unfamiliar voices, you tensed. Listening closely, you recognized your brother's voice and calmed down, continuing to scroll through your feed.

y/n in thoughts:

• Brother, it seems, brought someone... Oh well.

Then you heard them enter your brother's room and muffled voices could be heard coming from there.

After 20 minutes:

You were feeling a little hungry and decided to go to the kitchen to get something to eat. As you left your room, you headed straight for the kitchen. But to get to the kitchen, you had to pass the door to your brother's room. You walked calmly through, grabbed some chips, and headed back to your room.
As you returned, you saw your brother's door wide open. Sighing, you hoped to pass unnoticed, as you didn't want to be talking to a crowd right now. But naturally, that didn't happen.

As soon as you appeared in the doorway, you were immediately stopped by a voice. It was inviting, low, but very pleasant.

Nilu:
— Stop. Who the hell are you? And what are you doing in this house anyway?

You immediately stopped and began cursing this trip to the kitchen. Then you turned your head toward the room. You saw three guys there, and, as luck would have it, your brother was gone.

The first guy was Haruki. He sat quietly on a small chair, leaning back, and simply looked at you without any reaction, as if you were just another piece of furniture decorating the house. He himself was quite muscular. He looked to be about 6'3" tall, and he was 25. He had sharp features, a hooked nose, dark brown eyes, and black hair, pulled back with his hand. His Adam's apple was very prominent.
