Mark hummed and nodded in understanding after some time.
"Well, I guess it's not the worst way to spend your free time. Sometimes, people just like being alone."
Mark did not expect the look on Luna's face to suddenly change from her blushing embarrassment to a contemplative look that made her appear very downcast. Her eyes clouded over, and a mask of sadness appeared on her face as she was transported to another place inside her head. Mark leaned forward and called her name, but she did not answer him the first few times.
"Luna!"
"Huh?"
Mark finally shouted her name loudly, and Luna seemed to snap out of whatever trance she had gone into as she looked up at Mark in shock. She saw the worried expression on his face, and she smiled.
