The story is still ongoing how would you know the end? Even Korean version is only up to chap 100 (from what I heard this series is going to be 120 chapters long). From here on it seems Daon starts to think about Sunghyeon more and more tho he still prioritizes Jaemin and succumbs to his every whim.
I just hope that what happens in later chapters is the continuation of how Daon interprets what Sunghyeon said in chapter 85 about confirming what Daon is actually feeling towards each of the three suitors and thinks through what Daon really wants.
