Bound by Chaos by Hayweerc
https://archiveofourown.org/works/53434105/chapters/135245236
Set is a fantasy world that is heavily inspired by attributes of DnD and other related rpg fantasy realms.
Shadow (a blood hunter) had an encounter with a rampaging werewolf with the intent to slay it. The blood hunter and the werewolf, who turns out to be Sonic (a rogue), were on the verge of death until they were healed by Silver (a druid) with a shard from the master emerald.
Accidentally, Silver may have also placed a curse on the pair. They cannot be separated and are bound to each other’s presence. Shadow isn't too happy with the situation, and learns to cope as he journeys with the two- encountering other characters and monsters as they search for a way to break their curse.
Not long though, Shadow starts to see the weight of the trauma held on Sonic's shoulders as he struggles to contain his werehog form.

Sonic’s brows furrowed in worry.
“Are you still not feeling well?” Before Tails could protest, he added, “I know when you’re lying to me.”
“No, I’m-” Tails needed to remember to do something about this next time. The conversation always frustrated him, “I’m fine now. Better.”
“Tails…” he pushed himself away as Sonic reached out; with hurt evident on the his face, Sonic pried, “what’s wrong?”
