The culprit

"Have we met before? You look quite familiar." Nathan held his chin in thought as he scrutinized Shera's face. "That's not right. I must have gotten it wrong…of course, Leo wouldn't date a gangster." 

"Gangster?" Shera glared at him. 

"I'm not saying you look like a gangster!" He corrected himself quickly before Leo could react. "What I mean is, I just thought for a moment that you hold quite a resemblance to a terrifying demoness—Shera Black." 

Leo laughed while Shera raised an eyebrow. "You think I look like Shera Black?" 

Nathan scanned her thoughtfully. "Just a little." 

Leo shook his head. Was there anyone who didn't know Shera? He exchanged a look with her, and she pretended to not notice it. 

"I would very much like to keep you company, but I have things to do." Nathan excused himself. "You two enjoy yourselves, okay? Feel free to call me if you need anything." 

As soon as they were alone once more, Leo scrutinized her face.
