Under the community tab, you can look for lists. These are lists users make of their favorite dramas or dramas with certain vibes or genres. You'll find lots of good dramas to watch, and, if your tastes align, friend the list maker. Friends have helped me broaden my tastes. I started out with K-dramas, but I'm watching mostly C-dramas at the moment (less angst!), and I enjoy an occasional J-drama.
I especially appreciate reading reviews from my friends. I find excellent dramas to watch, and it's fun to see their reactions to some of my favorite dramas.
I see you've watched WLGYT. I haven't because I'm avoiding tearjerkers right now. But, if you like nostalgic shows with a few tears, Twenty Five Twenty One and Reply 1988 are good. If you like a magical, supernatural show, try Twinkling Watermelon. If romance mixed with melodrama is your thing, watch Crash Landing on You.
If you have any specific questions, feel free to ask.
