Yuri, Taeyeon and Sunny were devastated to know of Yoona's, Tiffany's and Sooyoung's dating news. 

Yoona had been dating Yuri on the sly while the black pearl was kept in the dark about Seunggi. In short, she didn't treat her relationship with Yuri seriously. The day SM confirmed their dating news, was the day Yuri had moved out of the dorm and bought another apartment. 

Whereas Tiffany had gone back to Nichkhun even after he had let her down once. She had replace Taeyeon right after the Thai prince came back. Was Taeyeon not enough for her?

Sooyoung and Sunny weren't in any relationship but the younger girl knew of her best friend's feelings for her and chose to keep quiet. Sunny is hurt, and she is done with Sooyoung.

Yuri and Jessica were best friends and simply enough, if Yoona had hurt Yuri, she had hurt Jessica as well. No one was allowed to hurt her best friend and mock her like that. Tiffany, on the other hand was also very close to Yuri and Taeyeon didn't mind, she knew how to differentiate personal feelings and friendship. 

Hyoyeon was close to all of them, and it hurt her the most to watch her girls like that. 

Yoona left Yuri for Seunggi.

Tiffany left Taeyeon for Nichkhun. 

Sooyoung left Sunny for Kyungho. 

Was it really worth it? 

Now it is all up to Hyoyeon, Jessica and Seohyun to solve this mess as well as the 3 heartbroken girls.
