Zongman: They All Believed the Diary I Wrote

As long as I write a diary and let the person who has the copy of the diary believe it, the content of the diary will come true?

If so, don't blame me for making it up.

As a time traveler, Suho-sama knows how to write this diary.

But while I was writing, how come these two-dimensional heroines are all around me?

Oh, the diary copy holder, that's fine.
