I Have Crossed Over, but You Are The Second Week?

After the rebirth, Subaru Nayuki couldn't remember the events of his previous life for a long time, but what he didn't expect was that he, who had been reborn, actually traveled to another world again.
And the 'system' that seemed to be of no use other than chatting and bickering, which I originally thought to accompany me growing up, did suddenly release a mission in another world? And it still has rewards?
However, who is Emilia? What if the mission reward is a chat group?
What Subaru didn't know was that what he was about to embark on was a journey that could not be turned back, and would be a journey full of 'wings' behind him.
(This book is not a pure re0 doujin, including other characters and worlds. Currently, the chat group characters include Tsukiyomi, my wife Yuno, Nangong Nayuki, Wugeng Liuli and Sakagami Tomoyo. (** Gong novel, not a CP party, likes to say xxx Do not disassemble, do not enter. ))
