The morning arrived. Jeongyeon woke up finding Mina sitting next to her while looking at something on her desk. 

"Good Morning, Mina" she yawned. "What are you looking at?" 

The girl pointed at a cube. 

Jeongyeon stood up and went for it. She turned to look at Mina.

"This is a Rubik's cube" she gave it to the girl, who amazed by the colors started to rotate it in order to find all of them.

"Maybe you don't have this on your planet, but it is really fun" Jeongyeon took it again from Mina's hands. "Look, as you can see, this side is red, this one is blue, this is yellow, then green and this is white." Jeongyeon mixed the colors, but then Mina put a worried face and took again the cube. 

"Oh no, it's okay" Jeongyeon explained. "That is the purpose actually, I have to mix it and to solve it each face must be returned to have only one color" 

Mina took the cube as she was having the most precious thing in her hands.

Jeongyeon looked at the clock and she screamed .

"Damn! It's already late!" She stood up and she ran right to the bathroom. She came back in her clothes. 

"Ok, listen, M1" she took the girl's shoulder "I gotta go. I know we agreed to take you to the school but I have to talk with the principal first. Please wait here until I arrive. Don't go anywhere" she told the girl who only nodded. 

Jeongyeon ran to the stairs and left.

When she arrived, Sana, Chaeyoung and Nayeon were already waiting for her. 

"Where's Mina?" Chaeyoung asked her holding her hands in the pocket. 

"She stayed at home" Jeongyeon shrugged. 

Suddenly Momo arrived. Her neon pink jacket was impossible not to look at. 

"Who stayed at home?" Momo asked Sana.

None of them spoke. They looked at Jeongyeon. 

"Uh...My..." Jeongyeon stuttered "My friend" 

Everyone slapped her in their mind. 

"Your friend? I thought your only friends were Chaeyoung and pretty Nayeon!" Momo said with a confused tone, but she received a nudge in the stomach from Sana. " I mean, chaeyoung and nayeon!" 

"
