Sana didn't know about what happen to Tzuyu. But she actually hurt not because she fought with Tzuyu. But because Tzuyu's word is always repeating to her since yesterday. Thinking that because of her anger that takes her. She doesn't have a bestfriend anymore. She believes that it's her fault why their bestfriend relationship is gone and done. She also believes that if only she confront Tzuyu in a nice way they will be friends again in a few days. But she didn't. 

Flashback~

After Tzuyu said his words and runaway. Sana feels her knees are breakingdown. She sat on the floor while crying. She didn't even bother herself to think about Jimin. She just sat there and wait until Tzuyu is already gone to her eyes. 

On the other side, Chaeyoung and Dahyun are waiting until the scene is done. Jimin's friend help him ( Jimin ) to stands up and go to the clinic. While the Twins (Chaeyoung and Dahyun) help Sana to stand up.

The two brought Sana in Minatozaki's house and comfort her for a minute. While comforting Sana to what happen. The twin got a text from their parents to come to the Hospital and said that Tzuyu is in Critical stage. They quickly tell Sana that they have to go home.

Sana wants to ask the Twin but never had a chance to as she sees the Twin runaway after biding their goodbyes.

"If only I did not say those words..... those words to hurt me and Tzuyu. I know I will not be suffering in this situation." she thought.

She cries and cry again until she fell asleep.
