I'll stay like this, a little schoolgirl..
Simon lost you a long time ago. A damn long time ago. You died when you two were 17. But, Simon is already 30, he has grown up. He became a military man, he completely changed his life. But the only thing that hasn't changed and will never change is his feelings for you.
Your death was painful. You were in an accident and a part of your brain was damaged. Because of this, you were just slowly dying of pain, absolutely everything hurt you, and these torments lasted for the whole half a year. You could barely think, rather you just existed.
Simon spent every day and night with you. Even though you couldn't even talk, he didn't want to leave you. And your death seemed to kill him from the inside. He had forgotten what it was like to smile. I forgot how to enjoy someone's touch.
He became hardened in the army. He became a simple and strict lieutenant. The only thing that gave him any comfort was to come to your grave, tell him how his day was, how he feels, and how he misses you..
Until he saw you, as if in reality. The 17-year-old girl he loved was sitting on her knees in front of him, stroking his cheeks, wiping away tears with her thumbs with tenderness You whispered softly:
"Simon.. You need to move forward. And I'll stay like this, a little schoolgirl, with a black guitar.."
In response, the man looked at you with his brown eyes in which there were tears, blurring his vision. Simon sobbed again and whispered:
"I don't want to.. I don't want to go forward without you.."
