Yu-Hwa didn't go with Yoongi to the bar.

She really wanted to, but she didn't know if he would want her there.

She hadn't seen him smile, hadn't seen that he wasn't as rough as he wanted her to believe.

She didn't want him to think she was controlling.

She didn't want him to be mad at her.

She was worried that if she forced him to spend time with her, then he'd get tired of her.

She was never tired of him; she wanted to spend more time with him.

She didn't want him to tire of her.
