@Natzume i know what you mean. This is still happening to under the oak tree. I found the story on another site and continued reading it there. I have yet to find a different site of this story yet though. Rather upsetting.
@AlysHatter https://bato.to/series/90083/saving-my-sweetheart-official This is the website where I was reading the manhwa but unfortunately it also stops at chapter 108. THE INDONESIAN TRANSLATION IS AT CHAPTER 121
