the accurate setence might be 제가 솔로인 것을 보면 잘 알겠죠 if literary translated it into english, it might be 'As you see that I am single, you know (about) it well' The meaning still depends on the context though. The korean guy answered first doesn't really know the difference between 'solo' & 'single', as same as, he said the 'konglish' word has been used on Korean website. I didn't really answer for korean language, but in this case, I gotta point it out, lol

"솔로" menas "solo". but nowdays, "솔로" mostly means what haven't girlfriend or boyfriend status. it was started in internet. Actually, korean uses many many internet idiom. it's very difficult.
