Sugawara wonders if this is how he gets his heart broken.
He had a practice yesterday he forgot to tell you about, and he ended up accidentally standing you up, which has led to him being ghosted.
It most likely isn’t deliberate, Suga reasons hopelessly to himself. He shouldn’t react too extremely yet.
Maybe you’ve simply lost your phone, or found yourself in a situation where you’re unable to use it; or perhaps you’re asleep. He remembers you tend to neglect all calls and messages before twelve in the afternoon, being too lazy to check them before you’ve fully woken up from sleeping in.
Still, he’s not out of the woods until he gets a reasonable explanation from you. Face-to-face. After all, in Suga’s mind, there’s more negative possibilities than promising ones in this predicament.
Before he theorizes himself into a panic attack, however, Suga forces himself to raise his fist to the door of your apartment. He’s been pacing for ten minutes since the security guard let him into the complex.
He knocks once. Then, on second thought, he knocks a few more times. And then he waits, expecting the worst of all possible worlds and denying himself the respite of hoping.
