yup gocchin is shy in her own way, and i suppose she doesnt wanna talk much about her own life because she dont want to coz any conversation that will be an advantage for the paparazzi, we all know how popular gocchin is, and the paparazzi is like stalking her 24hr, so its like shy + self-defensing same time.
back then when she was in mm, i suppose when one person is in a group they wont stalk u so much, but now gocchin is solo, so she just have to be a bit more careful of the paparazzi. so she is just being on-guard 24/7. her personality hasnt change at all, just being more careful ^O^ a few months ago i thought she had kinda change somehow like she was cold, she was extremely quiet on HMs but after watching some making of, like GNP, she was her adorable self again. then i realize back on hm she is just being her shy-old self when she is around every1. so she havent change, except being more n more like an artist and looking more beautiful everyday ^O^
