Soulstar has dropped a MV teaser before the release of the first of their two upcoming songs, "Happy Ending".

The teaser is short, showing a man and a woman (played by well-known Japanese actress, Hyunri) standing as they introduce themselves through narration.  Nothing else is revealed, raising curiosity about their relationship, so it looks like fans will need to wait for the full release!

In addition, "Happy Ending" was recorded before member Lee Kyu Hoon enlisted in the military back in December, so fans will especially be touched to hear his voice again in a new track.  

"Happy Ending" will be released on September 26 while the second single, "The Start of a Relationship" will be out in October.
