If you mean in REAL time, I'm not likely to start writing a sequel sooner than February. If you mean passage of time for the characters, there's a decision to be made there:
1) Pick up very soon after previous ending, with Ni-Wa and Lu-Mao still in their first year of marriage? Or--
2) Jump farther forward in time, to enable depicting a romance between Lu-Mao's son and Rahayu's daughter?
