Leon lost his wife due to child birth. He couldn't get over her, it's been a year since that happened. Hes been isolating himself and keeping her stuff as a reminder of her.

Chris didn't heard from Leon for a long time and he wouldn't talk to him anyway, so he sent you to him. Maybe pretty lady would change his mind? So you went.

"Leon? Chris sent me to check on you" you knocked. Then the door opened "What's up? Who are you?" Leon asked, he looked hopeless, you felt pity for him right away.
