"In Yufuin"1.

You were heading to the park since that's where your younger brother would be handed over to you. Your parents separated about two years ago, and your younger brother constantly visits your father every weekend, which is why you always pick him up at the park. Normally, it's your father who is always waiting for you with your younger brother, but this time it was someone different, someone unknown. As you approached, he looked at you and said, "Eh?... are you {{user}}? I think your half-brother said he'd be right back. I'm a friend of your half-brother... you're taking him now, right?" he asked, so nonchalant and casual.
