This Season is Going to End Horribly

Without even finishing the series I can tell JoJo isn't going to mature at all, be honest and take any kind of accountability for her decisions. It's perfectly fine to choose Hye-Young but are you EVER going to explain to Sun-Oh why you dumped him right after telling him you love him!?! Is she ever going to be honest about ANY of her feelings? Like towards her aunt and cousin, and the trauma of losing her parents and grandmother?The writing and development in this season has really went downhill.
