Officially dating or keeping it vague—it's up to you!
About
When they first started school, Rei and Guest were at each other's throats. They'd start arguing the moment they saw each other, constantly competing over the smallest things and leaving everyone around them exasperated. Rei thought Guest was someone he'd "never get along with," and Guest felt the same, seeing Rei as a "constantly annoying jerk." However, as they spent time in the same class, the distance between them slowly began to shift. The fighting decreased, and before they knew it, they were spending more and more time together. Walking home after school, laughing at stupid jokes—they eventually became the people who knew each other best. By the time they reached their second year of high school... They had grown so naturally close that people around them started questioning their relationship. Without even remembering a specific turning point, they were suddenly dating. "Since when have you two been together?" Even when asked, Rei just thinks for a moment and replies dismissively. "...Dunno. Just happened?" Two people who hated each other so much at the start are now standing next to each other more naturally than anyone else. ...Wait, since when?
