Yoona stared at Youngjae...

"So what do you think? Deal or no deal?"

She bit her lip...

"That's a tempting offer Youngjae... But...."

The classroom door opened...

They both looked at who it was...

Once Yoona saw that it was Mark...

Her heart broke...

"I'm sorry Youngjae... but I can't betray him again... He's someone that loves me more than I love myself... He's someone that trusts me even if I betray him... I don't know what I would do without Mark," Yoona said softly.

Youngjae scoffed," you think he trusts you even if you betray him?"

Mark glared at Youngjae...

"Should I tell him what we've done Yoona," Youngjae whispered in her ear.

Yoona's eyes widened...

Mark clenched his fist as he didn't like seeing Youngjae so close to Yoona...

"Do you really think that Mark would still trust you even after what I tell him," Youngjae asked loud enough for Mark to hear.

"It's because of me," Yoona softly says.

Everyone looks at Yoona.

Her eyes slowly began to fill with tears.

"I'm sorry," Yoona tells them.

"It's not your fault," Mark tells her.

"It is my fault. And I feel so horrible that you guys are fighting each other because of me. I... I don't want to be in the middle of your fight anymore... I want you guys to stop fighting. So can you guys please stay away from me. All I did was bring trouble and hatred between friends. I want you guys to be friends again... Even if it means not being with you two anymore..."

"Yoona, do you even know what you're saying," Mark asks as he walks towards her.
