It's actually a subversion of the popular "crazy bf imprisonment" troupe. Normally we would see the mc being all freak out and trying to escape, ml going full yandere route (SA and so on), and were at the end mc would forgive all of the literal torture for the happy ending sake. Here we have mc who was like "yeah his behavior checks out, mf is crazy, but his effort is adorable" he said it himself he doesn't panic because he know he isn't in any danger, because in his eyes ml is more like a sad puppy than yandere bf. He himself was so insecure about being abounded that he both understand the crush out and is kinda comforted that ml cares so much about him leaving the relationship. They finally opening to each other about the depth of their insecurities. He sees that ml is in psychological crisis and that's why he's not so set about taking the collar off at any means possible, but rather to make ml feel secure enough so he wouldn't need a collar (psychical representation of mc being his and dependent on him) or financial dependence to calm down his fears.
