The God of Theater: Time Notes

(Drama God fanfiction + No CP + No Male Lead + Fictional Diary Format) As a three-hundred-year-old relic, I, Xu Tianyi, have always kept up the good habit of writing in my diary.

A certain notebook kept appearing in my bag. Even when I left it at the lost and found, it would return to me a few minutes later. Driven by intense curiosity, I opened it. It seemed to record another life of mine?
