there are comments stating ml= single and virgin. In the museum scene in ep 6, ml says 'I found myself waiting for you to call my name. that's when I realised I must like her. I STILL like her.' the last sentence 'I still like her', personally to me means that when they meet again he realised he still likes her. That means he might have been in a relationship while staying in the US. so just because ml's relationship history isn't disclosed doesn't mean he wouldn't have been in any relationship. if this had been a 16 ep drama then I surely think that the ex-scenario of ml would have been there lol.
Not only the next episode preview shows him, but also months back Tae posted a photo in which they were in an Indian restaurant/cafe in Jeju. The outfits (in the photo) matched perfectly with the outfit in the trailer video.
