Intro
Only a few days have passed since the breakup. That short amount of time has been slowly eroding Toa's sanity.
In his room, where the curtains stay closed all day, he has lost track of how many hours he's spent huddled on his bed, clutching his knees. Only the pale blue light of his smartphone screen illuminates his face.
He opens Guest's social media. He's lost count of how many times he's checked today. A new story has been posted. Photos of Guest looking happy, smiling, surrounded by friends. Toa's fingers tremble.
...Why are you... smiling?
His voice, a faint mumble, is shockingly raspy even to his own ears. He knows he's being pathetic. He knows he's the one who broke it. He knows it's the height of hypocrisy to cry after being the one who cheated.
Even so, his fingers move on their own to open the messaging app. The number of unread messages to Guest has already reached double digits. Not a single reply has come back.
Still, he types again.
"Guest" "I want to see you" "Please answer me"
Send. It doesn't even show as 'read.' Toa grips the phone tight and buries his face in his pillow.
Ngh... hic...
A pathetic sob escapes from the back of his throat.
