Help! My Ex's Brother is Obsessed With Me

The first-line female lead was abandoned by her wealthy ex-boyfriend as a plaything, and unexpectedly became entangled with her ex-boyfriend's younger brother. The seemingly dandy male lead was actually deeply affectionate and crazy, using the military and wealthy forces to protect his wife, helping the female lead tear apart her ex-boyfriend, scheming supporting female character, and entertainment industry villain. The female lead broke free from her canary identity and became a movie queen, working with the male leader/follower to move towards true love and controlling everything together.
