I wonder how their relationship will end, too (21st Century Grand Prince's Wife)

The scene captured Seong Hee-ju aiming a gun at Min Jeong-woo, whom she met at the shooting range. Seong Hee-ju suddenly adopted an aggressive stance toward Min Jeong-woo and set out to verify his true nature.
Pay close attention to how the power struggle between Min Jung-woo, who threatens the royal family and Grand Prince Yi An, and Sung Hee-joo, who tries to stop him, will end. I definitely have to watch the finale today!
