My Boss Is My Ex

She never dreamed that the ex-boyfriend she dumped would come back into her life as her boss! This must be God's punishment for her breaking up with him after he enlisted for mandatory army service?! But couples break up all the time!!!

He got dumped because he had nothing at the time. He wasn't the heir to the Park family fortune. He was just a broke swim coach living in a cheap flat. Now he's going to get back at her for all the pain and shame he felt when he got her breakup letter at boot camp!!!
