I suggest:
1, Tao Zhe, Jolin Tsai-"You will marry me today". A classic wedding love song with a very romantic atmosphere.
2. Liang Guang-Fairy Tales. The love between the prince and the princess is no longer just a fairy tale, but has become a reality today.
3.F4 "Never lose you". It's very suitable for you to sing together, and it won't be messy. Very cheerful and romantic.
4. "True Hero", I don't think I need to say this song.
5. Muji "By Your Side"
Brother Xueyou's song is really not suitable. You should choose a song with cheerful rhythm and romantic and warm lyrics. What I recommended to you above is in line with the atmosphere of that day. Please refer to.
