I'll give this a go :o
International lawyer, Clara Astley, returns to her motherland after twenty years for one thing: revenge. Masking her past identity as Cha Soo-hyun, an heiress to one of the wealthiest conglomerates in South Korea, she is on a mission to take her rightful place and reveal the truth from twenty years ago. In a twist of events, she ends up proposing marriage to her former fiance, Kim Joo-hyuk! But will he even recognize her...?
Season 1 is finished and Season 2 will be released this weekend! Also, a note; although it is primarily a romance novel, it'll be focused mainly on Clara's revenge and her realization that sometimes the truth isn't all black and white! ^^
