About the title "Solomon's Knot": It is composed of two intertwined rings, with no beginning and no end, symbolizing eternal and indivisible relationships, and symbolizing infinite love and faith in Celtic culture.
"Actually, the stupid person just wanted to find a knot similar to the Möbius strip, but he didn't expect it to exist. The origin of Solomon's knot can be traced back to prehistoric times, much earlier than the Möbius strip."
There is no plot, it is very short, about 10,000 words, you can read it if you enjoy it, and exit in time if you feel uncomfortable in the middle.
Clearance: Narcissus and Xiao Yuan's background have not been changed at all. Well, so he has a deceased wife, so he is considered unclean [holding his head]. There may be treasures that you don't accept, so don't force yourself.
The main reason is that stupid people think that this is the actual experience of Xiao Yuan in the original work, and it is the real him, so he does not change his experience.
Purpose: I hope that all world lines will be happy.
