Season 1 is over. I pretty sure that's what she meant
89.1 is mis-labeled. It is actually the epilogue that comes after the very last chapter. It was free to read on lezhin.com so that's probably why it's here. The series is over and completed with a total of 92 chapters, the last 3 of which still require payment to read (I have read them).
As for the epilogue, Seo Wan certainly did get his just desserts, and it was good to see that Jihye might finally get her own boyfriend...
Wait is this really over? The chapter 89 says 'to be continued' but 89.1 has the author note saying it's over x_x
