I recommend the novel "The tennis teenager, Kunihiro Tezuka." It was a Doujinshi novel about the tennis prince, and the male protagonist was Kunihiro Tezuka. Although the female lead did not remember the long scar wrongly, the story was very interesting. The relationship between the male and female leads was complicated at first, but later developed into deep love for each other. Friends who like tennis and sweet stories can watch it. I hope you like my recommendation, Mwah ~😗
Overall, the characters in this manhwa are well-developed. They have their own dreams, fears, and motivations that drive the story forward. For example, the main character shows great determination and growth throughout the plot.
The story could center around how the guard dog becomes the girl's loyal companion. Maybe there's a mystery they need to solve or a journey they embark on together.
