Based on your needs, I recommend the following novels: - " Addicted to Devil's Pet: Wifey, You're So Sweet ". It was a story about a devil male protagonist who turned from a tsundere into a gentle, wife-loving demon. - " The King of Hell's Addicted Little Princess Consort " told the story of a female protagonist who became the King of Hell's Consort after transmigrating, and the male protagonist who was in love with her was full of love for her. It was a strange story from ancient times. - " Senpai is Too Tsundere " told the story of a sweet and youthful campus love between the female lead and a senior. It was pure love for youth. The above is my personal recommendation. I hope you like it.
