Decoration purpose?

Shin Wu drove Irene to the hospital but she had lost consciousness. Lee Rang's car was following him. Yuri was mad at Lee Rang for not telling her about Irene's family condition and Lee Rang was mad at Yuri because of Yuri's childish behaviour.

As they reached the hospital, Suho had already arranged an emergency room. Doctors took Irene to ICU. They called Irene's family. 

Chen called Soo Hyuk and informed him about all the situation. Soo Hyuk left for the hospital. Suho was inside with the doctors and he examined Irene. He came out and whispered in Chen's ear, ''She will get cardiac arrest any time during surgery''.

''What?'' Chen asked as he glanced at Yuri.

''Don't let her know''. Suho said and Chen nodded.

Shin Wu glanced at Yuri and saw her crying. She wasn't letting Lee Rang or anyone come close to her. He walked towards her and sat next to her, ''Yuri!'' He called her name.

Yuri gazed at him and looked away.
