Seeing that two strong men standing in front of her, with their panting faces covered with sweat, Katrina knows she must have worried them. Just now before boarding the plane, she turned off her cell phone. She didn't think they would be so anxious just for her absence of all morning. Maybe because these days her mood was really bad and she looked very terrible, which feared them a lot. Katrina feels some unspeakable guilt. Katrina lowers her head and apologizes in a low voice, "Sorry, I am sorry to have you worried again..." She wanted to leave quietly and alone, and contact them after the plane lands. Who knows, there is a change during her plan. Next time, if she plans to leave, even if how embarrassed and terrible she is...... She must tell them in order not to let them worry
