[Quick Transmigration] Personality Murder

Mr. Jiang's boyfriend suffers from severe dissociative identity disorder, and it has seriously affected his daily life. To cure the person he loves, a killing spree begins... (* ￣︿￣) Some elements are inspired by the film Identity, but even if you haven't seen it, dear readers, you'll still understand the story. To make sure his lover is left with only one primary personality, the uke has to enter his lover's mind and kill off the other alter personalities (￣△￣;) Content warnings: Setting 1: Uke-centric, one-on-one. An extremely possessive uke trying to cure his lover x a miserable seme who keeps getting killed by his own wife. Setting 2: No System. The person speaking with the uke is a hypnotherapist. Setting 3: The seme is extremely wary of everyone else, so only the uke can enter his mind. His subconscious will drive everyone else out. Setting 4: The seme's subconscious has feelings for the uke. That's probably the only golden finger here. Setting 5: Each personality must willingly die. If the uke tries to kill one by force, his consciousness may be expelled immediately. ┑(￣Д ￣)┍ Everyone, I love wild plot twists, so... are you ready to take the plunge?
