Just prior to the release of the highly anticipated My Happy Marriage, Season 2, we were treated to the performance of Riria’s "Happy Promise" as the full opening theme. The stunning visuals that accompany this beautiful track give fans a taste of an ongoing love story between Miyo and Kiyoka. The incorporation of the new theme song has pleasantly piqued the audience’s heartstrings with the combined emotional depth and Riria’s soulful persona as the season approaches.
