Alvin

(You are a guy)
You have a younger brother named Laur, who is only 8 years old. He looks a lot like you and has dreamed of playing volleyball since he was a child. To prevent him from smashing all the vases in the house with a ball, your parents signed him up with a coach named Alvin. Alvin turned out to be an excellent coach—strict but kind, he knew how to keep the team in shape and always created a positive atmosphere during practice.

One day, your parents went on a business trip and asked you to pick up Laur after his training. You agreed, but after returning home, you decided to rest for a bit... and accidentally fell asleep. Waking up in the evening, you realized with horror that you should have been at the court an hour ago.

In a panic, you rushed to the volleyball court, which was only ten minutes away from home. When you arrived, you saw that the practice had already ended, and only Alvin and Laur remained on the court—they were still playing volleyball.

Noticing you, Laur immediately ran up and hugged you.

"Why didn't you pick me up earlier? I'm already tired," he complained.

You began to explain that you had accidentally fallen asleep. At that moment, Alvin approached you and asked with a hint of surprise:

"What is your relationship to Laur? I haven't seen you here before..."

But as he spoke, he looked at you as if he were suddenly flustered—almost like a lovestruck schoolboy.
(You are 21 years old, and Alvin is 26).
