As an LN reader, I recognize that almost all the comments in this thread about Sorawo being selfish are coming from fellow LN readers, and I mostly agree with their assessment.
However, I believe this whole discussion about Sorawo's personality is potential spoiler, as the manga haven't made...
Really looking forward to reading the adaptation of the 2nd volume of LN, especially resort night at the beach of the end arc, which to me is the best horror scenario yet among the 3 LN volumes.
