While reality hits hard to work in a luxury retail store, Mi-seo holds back thinking of her marriage with Jin-wook who dated her for 3 years. As Mi-seo finds a house at price below its market value, she pays a provisional deposit despite Jin-wook’s concerns. She scrapes up the money for the lease but is short of ten million won. In the meantime, Mi-seo’s friend Soo-jin tells stock information that drives Mi-seo to buy the stock. As she makes a profit, Mi-seo buys more but the lease deposit ends up halved and her marriage also breaks. Mi-seo struggles to recover the principal and encounters Sun-woo who is a mysterious convenience store part-timer.
