   Summary

   Wherein Est is a repressed mess who has spent a year and a half pretending he doesn't care whose bike is in his parking spot, and William is a territorial disaster who finally goes on a date with someone else just to see if Est is still capable of feeling anything at all.

   When a viral video and a family medical crisis strip away their "casual" armor, they’re forced to choose: keep their perfect, lonely reputations, or burn everything down to finally belong to each other.
