Which KDrama should we watch? (Patreon)

To not get bored of True Beauty, I was wondering what we should watch alongside it? We watched Snowdrop and Dearm (the first episodes), and both were great! But I was suggested Reply 1997 and i think Imitation looks fun. I think I was suggested Reply 1988, but i wanna go in order cause we'll eventually watch the series even if it doesnt win the poll.
