Han Shuang was a bit surprised at first, then burst out laughing abruptly. Immediately, she realized it was a bit impolite to laugh and turned her head away. Yet, she couldn't help but continue to shake with laughter, having never seen Chen Kai with dark circles under his eyes before.
Chen Kai knew what she was laughing at. Although he was somewhat unhappy, he could not get angry with a girl like this. So, he could only sigh.
"Go ahead and laugh. My appearance is due to a reason. You don't need to turn away."
Han Shuang could easily guess that Chen Kai must have been tangled up with that girl last night. Despite not knowing what had happened, she suddenly felt less happy.
So, she stopped laughing, turned her face to him, and looked at Chen Kai seriously.
"Are you wondering why I showed up in your office?"
