BEST SECOND COUPLE STORY

Can I just say, they basically stole the show. Despite the lack of skinship, the actors portrayed a splendid job in their roles. This is basically a story of a reverse common trope of rich or noble boy and commoner girl. We have have a saying in Filipino "suntok sa buwan" means impossible thing to happen, and Hao du basically did a "suntok sa buwan" task to win Lei Yan' heart.

Moreover He is a tsundere, the cold soldier falling in love with the pure, innocent but strong willed princess.

Lei yan is a princess, Tang princess, THE ONLY TANG PRINCESS AND Hao Du is a mere soldier, an adopted soldier of an official with low origins and He ends up marrying the princess
