Even though Bekah has graduated from�After School, it looks like she's been reminiscing about old times as of late.

Yesterday, the rapper-singer posted an Instagram photo on her Twitter, tweeting, "I miss you guys!" The photo features Bekah with f(x)'s Amber and SHINee's Key. As she explains later, the photo was taken at a personal friend's art gallery showing in Seoul.
