Meanwhile, in TWICE's dorm.  All the girls were crowding up around Nayeon's phone.  

They waited and waited.  Finally they received a text.

Jae: Sorry, for bothering you in the middle of the night, I am Jae, the boy that borrowed your unbrella earlier of the day.  I am sorry but I am busy in the next few days, I will return your unbrella on Friday.  Is that fine for you? 

"Ahh!!" All the girls screamed in excitement.

"Should I reply him?" Nayeon asked.

"Definitely." Jungyeon said.  Then she grabbed Nyayeon's phone and typed:

Sure, I will see you on Friday.  I will message you when and where to meet. :)

Jihyo stopped Jungyeon from hitting the send botton.  

"Wait! Guys! Cheer up." Jihyo said

"What?" the others questioned.

"Our song, Cheer up!" 

"Oh, I get it!" Dayhun laughed with Jihyo.

"Can someone explain what is happening?" Mina asked.

"A girl can't show her heart too easily.  She started to sing that line.  Nayeon can't show her heart that easily." Dayhun answered.

"Ohh.."

"But that is so stupid..." Momo said,  "What if he doesn't get it and give up?"

"Then he would not be Nayeon's boyfriend then." Chaeyoung answered.

"So.. Are we going to message him?" Nayeon asked. 

"Only if he message about the song." Sana replied.  

Everyone nodded expect for Tzuyu.
