Krystal loves him, but there is something about Choi Minho that absolutely kills her. 

Choi Minho doesn't understand. 

He doesn't understand when SM announce a dance battle and Krystal quickly raises her hand in the air, volunteering to be with him (even when Taemin's hand is on her shoulder, offering to be partners with her). 

But it doesn't matter, because Minho paired up with Yuri anyway.

He doesn't understand when Krystal is surrounded by so many people, being congratulated, being adored, and she chooses to go over and talk to HIM. 

When she chooses to go over and talk to HIM, even if he only ever gives her half of his attention because he's too busy talking to Yuri. When she could go to Taemin and he would have swooned over her, would have fallen at her feet and treated her like a princess like he always did.

He doesn't understand the way her heart skips a beat when those big, piercing eyes stare into hers. 

He doesn't understand that almost unbearable urge she feels to touch his hands when they are inches apart. He doesn't know how many nights she has dreamed of her hands safely enclosed in his big, warm ones. 

He doesn't understand the way she loves him so much.
