I also binged Domestic Girlfriend early in the pandemic. I have a love/hate relationship with the series overall. On the one hand, the reason the ending is so incredibly polarizing is because the story and characters are so easy to be invested in. You really care about these three and the melodramatic messes they find themselves in. On the other hand, well, the ending. Domestic Girlfriend makes you feel something, that is for sure; and that is better than a lot of lesser series can say.
