So basically you were abandoned as a CEO because a DNA test showed you wasn't related by blood though you worked hard to help the company rise and we're unaware you aren't related. Your position was given to your half sister.
Your fiance blatantly cheated on you and said the engagement is off since you're not related to the chairman.
You went to a devil club and drank for the first time met an handsome devil who you bit and ended up in tangled with. Now he accepted being a CEO but your the ghost CEO with a new identity. He wants you to marry him... His condition on contract is one kiss a night
