You and Felix have been broken up for a month.

You and Felix are under the same entertainment so you lived kind of next to each other in the dorms.

You accidentally went into the wrong building after coming back from a solo photo shoot, that building being the Stray Kids dorm room.

Once you entered you went into a dorm room thinking it was yours, but when you entered you saw your ex boyfriend, Felix. He was putting on a jacket.

When you entered he turned behind quickly and he made eye contact with you.
