The SNHG has announced today that a graduated veteran 1st-generation member of SNH48, who's been temporarily "borrowed" to a famous time-limited girl group under a different company after winning in a major talent contest last year, has now returned as a solo artist of SNHG as well as a member of 7SENSES, an elite subgroup of SNH48. In addition, SNHG has set up a separate personal office for her to handle her various works - an honor which's hitherto been given only to graduates who've been ranked #1 in their General Elections, which she hasn't (she was still a pretty high-ranking, "god 7" member, tho).

Here's the official announcement of that:
