A brain-teasing new fantasy romance web drama series starring Cosmic Girls's Seola, SF9's Jaeyoon, DIA's Ki Hee Hyun, BAE173's Lee Han Gyul and Doha, and more is coming your way on September 17 at 6 PM KST!

The story of 'Love In Black Hole' begins with the interesting theory that if black holes exist on earth, then so would white holes. A black hole would draw in objects in, while a white hole would spit them out the other end!

In the web drama's first teaser above, the story's heroine Eun Ha (played by Cosmic Girls's Seola) discovers that there is a white hole inside her room. Out of the many random objects which end up in Eun Ha's room, one is a love letter, dedicated to Eun Ha herself. 

You can join Eun Ha's search for the owner of the mysterious love letter when 'Love In Black Hole' premieres next month, via Big Picture Mart's official YouTube!
