"Chaeyoung-ah.. these past few days, we are like invisible to you. You didn't talk much. Is there something wrong? You miss Mina?" Dahyun ask Chaeyoung who looking outside the window, thinking about something.
"Yeah, Chaeyoung. Dahyun is right. You have problem?" Momo asked.
Chaeyoung look at them with sad face and nod. "I miss Mina."
"And you think we don't?" Dahyun said. "Chaeyoung.... Mina will be back in 3 more days. She just attend her aunt's funeral and nothing more. Why you look so worry?"
"It's nothing. I just.... missed to talk to her face to face," Chaeyoung said and continue looking the view outside the window, ignoring Dahyun and Momo.
'Did you notice it?' Momo whisper to Dahyun.
'What?'
'She started to change...'
'I know right.. i don't know what's wrong but i think she have problems and don't want to share with us.'
'I think, if we tell Mina, it could be help..' said Momo.
