The key point to watch in the second half is this, right? Hahaha.

The conflict surrounding their marriage is also intensifying. Prime Minister Min Jeong-woo (played by Noh Sang-hyun) opposes the marriage and heightens the tension by making a cryptic proposal to Seong Hee-ju. Queen Dowager Yoon Yi-rang (played by Gong Seung-yeon) also forms a conflict structure by showing signs of trying to use Seong Hee-ju as leverage.

Another romance line is also drawing attention. Choi Hyun (played by Yoo Soo-bin) and Do Hye-jung (played by Lee Yeon) from the 'Chief of Staff' group grow closer following the marriage of Sung Hee-joo and Grand Prince Lee An, forming a new dynamic. As they spend more time together, their feelings for each other are expected to gradually mature.

As such, '21st Century Grand Prince's Wife' is expected to heighten interest in the latter half as the romance of the central couple, the changing relationships among the four characters, and the stories surrounding the royal family and the Castle Group intertwine.
