A really good drama. I expected to be all about esports but there was sort of a sci-fi mystery and thriller to it as well. One thing that really hit me was all of the emotional scenes in this drama. I had tears in my eyes during many part of this drama. It was a good balance between bromance and romance too. I also like how each side character had a chance to tell their stories and we get to understand them as well. Glad they didn't went overboard with the romance so that was a plus too. The big brother little brother relationship was great. They both have their own female love interest though.
