After Qiu sent Chun back to the human world, a System came crashing down on him, and that was that.
Genshin Impact:
Zhongli: "You mean Qiu? He looks young, but in truth, I must call him my senior. Even solid rock is worn away by the passage of time, yet he hasn't changed in the slightest."
Venti: "Qiu? He's a very contradictory person. Even the wind wants to linger by his side, but then it wouldn't be free anymore, hehe~"
Qiu's world-hopping journey is tentatively set during the Archon War in Genshin Impact. The other worlds haven't been decided yet. It's a slow-paced transmigration story, though it might end up featuring only Genshin Impact.
I watched Big Fish & Begonia when I was young, and always felt that Qiu's world was too small. That's why he thought Chun was his whole world. I want to make up for that regret. Hopefully, I can finish writing it.
