Kai's grin wasn't infuriating. It was far past that. Ena knew she owed him a 'thank you' for the last time but she couldn't stand seeing that cocky grin on his face, as much as she could with the next guy.
Arms folded across his chest, he leaned sideways against the brick wall and smiled patiently, waiting for Ena to let it out. Her formerly pale skin now flushed red in anger and a tinge of embarrassment.
But without a word, she shoved roughly past him. If he wanted a thank you, she should be the last person he should ask. He would never get it from her because...well, Ena never felt grateful towards anyone.
Even when that person (almost) just saved her life.
