Here's my list of J Dramas since 2016 I've scored 7 or higher . Some of my favourites didn't make the cut because of that age cutoff, hopefully once you have the J-dorama bug you'll reconsider 😁
Kimi wa Petto (2004, alternative romance, role reversal)
Quoting the whole post to give another plug for Kimi Wa Petto - another 2004 romance to consider when ready would be Orange Days Shibasaki Kou, be still my beating heart! 😍😁
