Maybe my English is not so good, I don't really understand.
One player? but why does it say "they" later?
" Despite of this, they were dulled in December"
"Also, they haven't used a bouquet of flowers"
I would offer more solutions if it is only one player:
- He was duelled in another world
- He is duelled by the NPC opponent, whereas here he is attacking himself.
So in December he meets the Angry Customer on Monday, Wednesday and Saturday and knocks him out.
- He is a gamemaster and always duelable.
