When the female lead said that it really made me stop and think for some time, because I myself think I am still in that time in my life. But as someone who also had a first love that didn't work out, but still, that person is someone who ''means so much to me'' as the main couple in Twenty- five Twenty-one feel about each other... The series was amazing, and their love made my heart race many times, but I think it talks about a lot of inconvenient truths about love and hardwork. The results of effort grow in stairs and one shouldn't despair and give up if they are stuck, if they like what they do, rather than like being congratuled about the good results of their hardwork. Besides that, it says that love changes, life is made of choices and people are imperfect. Na Hee Doo couldn't do another relantioships in which one person is sorry all the time and the other is always waiting. Some people called that ''imperfect writing'' about her characther, but I don't agree with that. I thought it was very good writing. I have a very similar feeling about the end of romantic relantioships in ghibli movies: the main couple doesn't end together, but still the pain and happiness are feelings very precious. That's when you know you loved hard. In the end, Na Hee Doo said it best: There're very few things in this life we can do exactly in the way that we want.
