I recommend a time-travel novel called " Silly Koi Fish." The male protagonist, Yu Xiaoying, brought the koi back to ancient times and became a " silly " princess who was raised outside the palace. She came from a remote town to the bustling capital and began a new life of " stirring up trouble." Although I'm not sure if it's by the sea, the male lead comes from a small family, so he should meet your needs. I hope you like my recommendation, Mwah!
