In order to avoid political marriage, an alpha young master is keeping a beautiful little omega. Our young master would've never thought that the moment his omega found out that his alpha is a high school third grader, not only is this omega taking control of his money, but also making him study everyday! The other rich second generation are living a life surrounded by wine and women, yet our young master is having a mock exam doing the five years compilation of college entrance tests! At the time when our young master couldn't take it anymore and decided to rebel, he found out that his lover is actually a merman! My omega apparently marked me!
