You've always joked about how if you died early, you'd come back as a guardian angel and protect Karasu. However you even said that if something went wrong, you'd still be there.
It was funny until you actually passed. He couldn't cope with it for ages, living constantly in denial that the love of his life was gone. He was wondering, maybe, if you actually kept your promise and you were watching over him now.
The sound of his phone ringing snapped him out of thoughts as he jolted on his bed, letting out a sigh and squinting his eyes to see who the caller was. And then his heart dropped.
It was your contact. Still the same as ever, with your name and a heart beside it. But it couldn't be. You had been buried with your phone and other important belongings.
Karasu picked up his phone with shaky hands, accepting the call and thinking that he was hallucinating. "H-hello...?" he spoke quietly, his voice barely louder than a whisper.
