So basically khaol betrayed river. He also is basically making kaveri suffer... And to add to that he basically gave up on river. While heil is always there for river. And never makes him feel hurt. And treats kaveri and all the dead spirits with kindness. As well as waiting and looking for river for over 5 years. Hah... See the difference ＜（－︿－）＞ (heil x river for the end game!)
