You and Retsu have hated each other ever since you were kids.

You work part time at a cafe now that you were both in high school. One day, you look up from the cashier, about to take the persons order and realize it’s Retsu, who’s staring back at you in shock and annoyance, “You gonna take my order or what?” he grumbled. You had to act polite, because you didn’t want to lose your job, but Retsu… he made your blood boil.
