Mk glanced over and saw Frisk, not even noticing Chara with her. He stared at her for a moment, listening to what Sans said. He looked back at him and gave a cocky smirk. "You're always so full of yourself, just watch!" With that he was gone to get shot down, not that he thought he would. He was so sure that Frisk would say yes. He walked up behind Frisk, Chara looked over at MK who was standing too close to Frisk for her liking. Frisk looked up to Chara to say something when she saw the look on her face, then she turn, jumping a little at MK stand just inches away. "Oh! Hey MK, uhh. Whats up?" She said with a small smile, taking a small step back from him. "Hey Frisk! Wow, you look nice today." Frisk laughed a little. "aww thank you, that's sweet of you to say." She said politely. "So, you haven't replied to any of my texts, and well...I was wondering if I could take you out one night. Maybe dinner, a movie..." Frisk was taken back. "As...friends?" Frisk asked, Mk smiled an shook his head. "Nah, I...I would like to try being more than friends." When he said that Frisk glanced at Chara, then back to him. "Oh, wow. Well you see. I'm, already...."Frisk was trying to find a nice way to tell MK 'no' when Chara chimed in. "She has a boyfriend already!" That was when MK noticed Chara. He wasn't sure what took him back more, the fact that Frisk had a boyfriend, or this human with piercing red eyes staring right at him. "...whoa...so, that's a no?" He said to Frisk, but his eyes never leaving Chara. "Duh! Now get the hell out of here before I do something you'll regret!" Frisk looked to her, frowning a little. "Chara!" Chara looked back at her sister. "What, I'm kinda having a shity day. I just want to finish shopping with you and go home." Frisk turned to speak to MK, but he was already gone.
From what Sans saw, MK and Frisk chatted more a moment before he could almost hear Chara raised voice at MK. Then Chara and Frisk talking while MK walked away with his head hanging. He approached Sans again, sitting on the bench next to him. "So, she already has a boyfriend. I'm not stupid, I know who it is." He paused before looking at Sans. "How long?"
