Love Alarm in general is very original and a great story. The actors do a wonderful job, and the writing is very well done. There are twists and turns and nothing is too obvious.

Love Alarm Season 2 is not a stand-alone drama. You must have season one fresh in your memory for it to make any sense. You need to remember the little things. I see it as the rest of season one, not a 2nd season.

I believe the low ratings are due to people not knowing or clearly remembering the story. I watched the first season one and a half years ago. I just watched Season 2 Ep 1 and was so lost. After rewatching all eight episodes of season one, it changed everything! Season 2 Ep. 1 seemed like I hadn't watched that episode yet - it made complete sense. The repeat viewing was worth the time.

Another possible reason for low ratings is that the two male leads were competing for the female lead until the very end. 50% of viewers were probably soooo upset that their favorite man didn't win, that they weren't able to forgive the writers. They soothed their wounded hearts by giving low ratings.
