She's laughing. He's telling her something that have made her laughed so hard that her tears fall out. He wipes her tears and laughs with her. She leans towards his touch like it's the most natural thing to do. Then she smiles at him lovingly, as he slowly pulls her in for a kiss.

I look away for a moment. I can't bear seeing her in another man's arm. But what can I do? All I can do is to look out for her.

I can only be her guardian angel.
