I don't think it's because of GYJ, but because part 1 was reallly a success, a hit, many wanted to know what's…
I don't think this person meant the success was due to GYJ only. The statement was meant to say that she's doing pretty well acting given that she is a rookie actress.
Anyone re-watching the fireflies scene in episode 4? For me this was the most romantic scene ever even better than the kiss scene. I can't wait for the ost for that song.
