You and Leon had a huge argument which leads you to walk out in the house and walk outside the street. There's were so many trucks passing by

"Watch out!!" he yelled, as one of the truck starts to come running towards you. He quickly pushes you off the street making him the one got hit by the truck.

5 months of him being unconscious in the hospital bed.

A he woke up, he looked at you with a blank face.

"Who're you?" he said with a serious face looking at you like a total stranger.
