It can also be seen from the title that Payne is the male protagonist. Pain is just Pain, not Nagato. The ending is beautiful and the process is happy.
Xiaonan and Payne are just childhood sweethearts, they have no JQ at all~!
As for the heroine, she came from time travel and likes Payne, so I wrote a retrograde story! . . .
It will be updated from time to time, so please don't wait carelessly (looking at the sky...)
