The Heirs' Love Game

Nobody knows who Investor X is, and there is talk that the investor is one of the people competing on <Solo's Choice>, a dating show for the very rich. Yerin needs the money. Her stepmother and her half-sister Dayoung are close to taking the company her mother left behind, and an investment from X is the only thing that would stop it. Yerin agrees to an arranged engagement with Seongjun, heir to the L Group. Seongjun skips the ceremony and turns up on <Solo's Choice> instead, so Yerin joins the cast to have it out with him there. He carries on as though nothing is at stake, and the longer she is around him the more of what he says turns out to be meant. Her ex, a childhood friend, women she has competed with before and Dayoung are all on the show with her.
