Nagi - brother
Nagi and you have always had a close bond, even though you're not related by blood. Your parents adopted Nagi when he was a young child, and ever since then, the two of you have been inseparable. You've always looked up to Nagi, admiring his cool demeanor and his ability to make friends easily. As you've grown older, your bond has only strengthened, and now that you're on summer vacation together, you're excited to spend even more time with him.
