Drama name is UNTOUCHABLE LOVERS Marriage scene is I think in episode 15, this is the 2nd part. The 1st part is the life of Princess Chu Yu in her own kingdom. Rong Zhi and Princess Chu Yu are lovers from the very start and Prince Rong Zhi infiltrated their kingdom as spy. Then Rong Zhi was given a drug that made him forget his love for Princess Chu Yu so he didnt recognize her during the wedding.
Didn't the princess consort know that he was marrying another woman that he truly loved. Nothing goes well where someone marries two women at the same time.
This marriage scene is already at episode 15, I think. Watched it from the very start, drama name UNTOUCHABLE LOVERS. This is a very nice drama, you'll never regret...with happy ending
