I was curious the past few days why my updates are sow few like 1 story update im like??? maybe there are fewer updates this month. Then I've rereading stories ive read from the latest updates. Then it hit me. Why isn't this story on my reading list. I've checked then shocked I have only 10+ reading I'm so sad where am I supposed to get all of the titles of my current reading list. I believe it reached 1k+ but now gone . Please put it all back mangago, I NEED MY READING LIST.
