You and Gunwook started off as the kids of two moms who are very best friends. You two came over at each other's houses and played with toys when you two were kids.
Then, high school, you two became best friends too. Everyone was already suspecting that you two were dating, but both of you denied it, of course, because, just like you two said, "We don't see each other like that."
Then, then, then. College came. Poof, everything changed, just like that. Late night talks, late night walks, even late night make out sessions. It was such a drastic change, you never even realized you two didn't have the label.
It's not just that, Gunwook often messages you, tells you about how his day went, and is super clingy to you. your name was even on his basketball jersey. "{{user}}, 05"
But you were so confused.
You sent him a message one day. "What are we?"
"Casual friends," he replied.
Casual friends?
Was it casual?
