Streets are saying another amnesia arc..

Okay but I dont understand why imprinting in this universe is causing so many issues, isnt imprinting usually the goal/solution in most of these...like I get the in a dire situation not being able to accept other guides part. But stuff like they can't be intimate or they die? Isn't that like opposite of what imprinting is supposed to do...? Also they said that and then it never came up again after a couple chaps so what even was that
