For whatever reason Sean was sent to war and you were a ghost haunting the fields he was fighting on. Since you found him attractive and not wanting him to live the fate you did you wanted to protect him.
"Heeeeyyy Sebastian! Need some help over here!" You hear from the land above you. It's been going on all day. Guns bombs and screaming. With every scream another. Leaves the Earth. Yet you're still here. Still stuck in this stupid plane of existence!
You float up to the sounds to finally see the damage the war had caused. It wasn't pretty obviously. It was a war. The damage though was worse then you expected. Bodies littered the ground to the point it looked like there was no ground.
Only two from the one side remained. 'Sebastian' and some other guy. His eyes were a grey blue and his hair was a dull green. His body was littered with blood and hole and Sebastian was holding him on his shoulders and was dragging him to the base.
"He must be incredibly weak" you thought to yourself. You pity the poor bloody man. Something told you that he won't be able to leave like the rest of his squad and he would suffer the same pain as you.
In a seconds thought you possess Sebastian's body and carry he man to the base. The moment you reach the base, you quickly part from Sebastian and fly away from the pair.
Why? Because it's basic knowledge that if you possess someone they can see you. Duh. You successfully get away and watch from a distance.
You didn't make it though. Even with the speed you carried the guy. You saw his ghost leave his body. Instead of flying into the sky or dropping into the ground he just stood there in a daze.
Tears stained his face as he realised what had happened. You quietly walk up to him and wrapped your arms around him. You quietly whisper welcoming and happy things.
He shuffles around in your arms. And lays his head on your chest. You gently ask him "I'm sorry for your lost but may I ask what is your name?"
His quiet sobs slow to a stop. However he does not move. "Sean" you hear a barely audible sound. You lift you head to become face to face with yours. With area are now a dark dull blue and his hair is a dark dirty green.
Unknown to you he slowly leans in and kisses you. With little hesitation you return his kiss. A light and happy feel enters you body. You look up at his face. The light from his skies reflects off you faces. The two of you were in the sky. You were finally in heaven.
