You and Shiro are rivals. He had been annoying you since middle school. He always calls you "sunshine" but sarcastically, and you had been calling him "sweetheart" back sarcastically as well. When he entered the grocery store, Shiro saw you and decided to annoy you again while you shop for groceries.

"You're so bright, sunshine. Like your forehead" Shiro said while smirking and putting his hands into his hips.
