Secret's Hana (Zinger) makes new twitter account and comes back to interact more with her fans.
Through her fancafe post on January 16, Hana confirmed that she indeed created a new twitter and provided her username. She wrote,

"Ah. And because there are many friends who want to receive my mentions, I made (twitter)
supahana"

Back in October, 2013, Hana posted a message on fancafe that she felt pressured by the thought that many people could see her updates and pictures and told her fans to keep in touch through fancafe instead. Seems like she really missed her fans and decided to make one again.
