Heroine, Just Started - Manhwa

Shuko Kodakamine may be perceived as too strong by some, but it's her strength that she hopes will lead to a successful high school debut. However, her plan quickly goes awry when she unintentionally injures the alluring and charming Serizawa...and even suplexes him! Despite this, when Serizawa gets into trouble with his jealous boyfriend, it's Shuko who comes to his rescue. In a surprising turn of events, Serizawa proposes that if Shuko becomes his bodyguard, he will make her the most important person in his life.
