It was all for you, sweetheart 😭😭⚔⚔

The Cost by Blood_Stained_Fingers It was not concern in that dark gaze however, but a possessiveness and disturbed look. He turned Harry’s face to the left and right, smoothing his long fingers over Harry’s cold, cold scar. Riddle lowered himself down, so he was chest to chest with Harry, allowing Harry to clasp at his body in a tight hug. Riddle pressed his cheek against Harry’s, the bone sharp enough to cut. His long fingers carded through Harry’s thick, sweat-logged hair, pressing a scorching kiss to his temple as though Harry was fresh as a daisy. “Oh, my little one. We will fix you.” -- The cost of making a horcrux was steep and when Voldemort manages to kill Harry, destroying the horcrux within, Harry finds out the exact price of losing a piece of your soul. It made a cruel joke that if Voldemort loved his horcruxes, Harry should love them too.

A Rather Useless Inheritance by Blood_Stained_Fingers

Being a Parselmouth came with the inherent predisposition to understand snake behaviours and imitate them. It was relieving Harry wasn’t going to kill anyone with venom, nor petrify them with his gaze. But also, somewhat frustrating as it was all completely useless. None of the skills that came with being a Parselmouth would help Harry survive Voldemort. It might, in fact, have the opposite effect. For all Riddle's fury that Harry was the cause of his elder self’s defeat, he was fascinated by the fact Harry was also a Parselmouth. He had grabbed Harry’s face, turning him side to side looking bemusedly enraptured by Harry’s threat display. “At your age, I was imitating much more vicious snakes than this, Harry.” That may have been all well and good, but Harry didn’t feel very vicious. He felt very threatened and in over his head.

Either must die at the hand of the other by Metalomagnetic Voldemort survives the Battle of Hogwarts because Harry Potter had not been the one to kill him, as the prophecy demands.

Stars, Hide Your Fires by Audair, Ophidias (Audair) Riddle’s undivided attention snapped to him with the swiftness of shattering glass. His turbulent magic receded from where it had besieged the shop.  "You,” he breathed.  Coiling in leisurely motions, the eager tendrils of his magic reached for Harry, swathing about his limbs and neck and chest with a liquid, flowing fascination. "I’ve been looking for you,” Riddle continued, tilting his head to the side and sweeping his gaze over Harry. It was an appraisal that felt simultaneously like the raking of iron nails and the tender drapery of silk.  It was so familiar, and yet… so foreign. In the winding streets of Knockturn Alley, an intricate dance of mutual obsession unravels between twenty-three-year-old Tom Riddle and a time-travelling Harry Potter.

Harry would have way more emotional support in this AU of an AU. Not that the Slytherins don’t care about him, but having the unconditional support of people outside of his House bolsters him. One of the worst things Harry deals with in Listening Ears is the judgement of the other Houses. So, Hermione, Ron and Neville help to improve his emotional state. The collar also doesn’t happen after the first time because the second they find out, the three others basically riot. Hermione is vicious at this abuse of authority, Ron is appalled and is absolutely planning on sending a complaint to the Board and the Prophet (with Harry’s approval, of course) to destroy Dumbledore, and Neville is telling his grandmother so that they can get some political outrage going.
