Reincarnated Knight Hime, I Really Am Not a Shotacon!

Lin Mo: As a good young man who helps the old lady cross the road at work But one night while sitting on the roadside eating, he was sent to reincarnation by the Hundred Ton King who came from nowhere. He thought it would be time travel, but his soul was stuffed into the body of the silver-haired knight with a beautiful devil figure who died in the battlefield by the goddess of soul. It doesn't matter if you turn into a girl, at least you have the system by your side... But the damn system is inexplicably bound to some demon king! Looking at the former Demon King Harmonia in front of her, who had lost the fragments of her origin and transformed into a weak young shota, she thought she would hate him so much, but she didn't expect that her body would not reject him at all! Especially after night came, when he was connected to his dreams countless times, and when he was treated as ice cream by the Harmonia with full physical strength in the dream, there was an indescribable emotion in his heart... (I really can't think of a good introduction. If you are interested, check it out Orz)
