I recommend the book," I'm in a different world ", to you. The female protagonist fell in love with the male protagonist in various worlds, but the female protagonist lost her memory, so every life is full of surprises. The male and female leads might not be the male and female leads in the book world, but they are my male and female leads. This book was about a Taekwondo girl, Yu Yu, who had transmigrated to another world in order to complete a mission to make up for the regrets of the original owner's previous life. The male and female leads met when they were young. Later, the male lead left. When they grew up, they met again. The male lead recognized the female lead and doted on her especially. The male lead liked the female lead. I hope you like my recommendation.π
