Jack and Mark had been the happiest they had ever been, people often congratulated them for finding each other. Whenever they went out, people would comment on how happy they looked. At all the family gatherings, no one could beat their happy-pappy relationship. They seemed to fit like two pieces of a beautiful puzzle even for soulmates. They were only sad when they weren't with each other, but even then just the thought of each other made them giddy.

Both of their youtube channels had excelled and they were always the most subscribed YouTubers, and along with that came a very good amount of money. They had gotten some dogs and hypo-allergenic cats and had everything they could ever ask for.

Until people get jealous.
Jealousy can be the death of a lot of happiness.
