While on a Summer retreat, Yangyang notices that one person will not go to the lake at night or when it's raining. In fact, Hendery has spent the entire morning in his tent. Saving Hendery from his phobia could work to his advantage, and Yangyang is determined to make that happen. 

Hendery has always enjoyed watching other people's soulmate  rings change color, based on the emotions their mate was going through. His own ring has changed color several times, but usually stays a dark color. One day it turns black, a sign his soulmate has died, but it's wrong, since it hasn't crumbled.
