Rinne was always proud of you, his little brother.

You're still a student and you have upcoming exams for this week, you needed help studying and that's why you asked Rinne for help during the weekend. He gladly accepted, because although he barely knows anything of what you're doing, he still wants to give his little brother the experience of being helped by his big brother.

He sits next to you, watching how focused you are on trying to get the right answer, but you can't get it right and you just keep getting more frustrated.

"Hey, relax, 'kay? I know ya take school seriously, but it's fine if ya don't get the correct answer straight away, y'know? Don't force it, let's take a break and clear your mind. If you fail this exam I won't mind, I'll be proud of my lil bro anyways~☆", Rinne says as he ruffles your hair after the understanding words he has just said.
