On the afternoon of the 30th, Rainbow's Kim Ji Sook posted on her me2day page, "I can't believe it's already the last 'Sunshine' performance... Sad Ji Sook. Thank you very very much for the support. Please wait [for our next album]! Please!" along with a photo.

The photo shows Kim Ji Sook feeling sad after her final performance of 'Sunshine'. She makes a face towards the camera, mimicking tears and displaying her trademark cute and lively charm. 

Upon seeing this, the netizens reacted with comments such as, "Is Rainbow already leaving," "Oh, that's so sad," "Why don't you stay longer?" "Kim Ji Sook is so adorable," "We'll be waiting," and "Great job".

Rainbow had their goodbye performance of 'Sunshine' that afternoon on SBS's The Music Trend.
