If you asked me my opinion on season 2 when i was only at episode 6 I'd probably say it's boring and seems pointless, but as I kept watching it I realized it was much much much better than season 1, the breakup was pointless a bit but I feel like everything wrapped up well and ended up working out in the end for everyone. I'm also not sure if it's because it was season 2 but I found myself not hating Min anymore. I was frustrated a bit at certain parts though, like when Kimha just let Minji walk all over her and didn't fight back (adopting Dohas thing basically, it drove me nuts then too). I wish there was more Doha screen time, it felt like she was shoved to the back when there could have been good parts for her in the plot, it seems like she totally disappeared. I think Choi Bomin plays similar roles from what I've seen of him but he does play those roles well. I'd recommend you to watch this season a lot more than the first one, and I think you could get away with not watching the first one, all I have that makes the first one nice is nostalgia of watching it when it first came out, season 2 is objectively better.
