On July 8th, the fourth hint for After School's red and blue units was revealed! Pledis Entertainment tweeted, "Nana came to the office with a blue cell phone~!!�Will Nana be in the blue sub-unit?" Snapped with a playful expression, Nana can be seen posing with a blue cell phone. Although the pictures are said to be hints, it seems the members for each unit are still up in the air, as several members could be found switching colors with each new hint. Netizens commented, "Maybe Nana will be in the blue team", "This hint is too easy", and "I see a red light in the back, is that a hint too?" The final units will be announced at their official fan meet on July 9th. Source + Photos: BNT News via Naver
