   Summary

   For just one singular moment, Mack understood. Damien and Marc had known each other years, they had spent an insensible amount of years together. Of course, of course they would pay more attention to each other. But Mack was irrational, and he was pent up, 

   And right now, he was feeling awfully ignored.

   OR

   Mack gets devastatingly cucked and, knowing him, he can't just let that happen.
