It hadn't occurred to me until now, but as it turned out, Contracts for the same Illusory World were in fact possible.
Maybe it was my fault. Or rather, that was almost definitely what happened.
I guess, because the crown prince was infatuated with the previous Protagonist, and then the two of them were killed on the same night, her brother must have harboured suspicions and resentment towards Lucretia, leading to this outcome.
Even though I told her to just blame me for everything...
'Although, I did say that under the assumption that I would never return...'
Surprisingly, I wasn't as shocked as I thought I would have been. Perhaps it was because I had already learned the truth of the Tower, and further than that, witnessed the birth of a Protagonist on Earth, that the idea of a second Protagonist emerging in an Illusory World I had already visited wasn't so far-fetched.
Either way, wasn't it perfect?
