I found this drama to be one of the best I've ever watched. The plot starts slow and dragging with Mukai (Akaso) trying to be in a romantic relationship at all costs. However, he is not fulfilled even when he becomes able to date other female characters. I thought Mukai to be a silly character in this part. But, as the drama continues, I understood this happens because Mukai is lost. Something is clearly missing. He isn't able to identify what is important to him in life. Not only in respect with romantic relationships, but also with relationships in general. I think everyone faces this kind of existencial crisis once you enter your 20s or 30s. You feel devasted because your work does not fulfill you, even though you may be working with something you supposedly love. You feel confused because you start relationships that exist for the sake of not being alone. You realize that being independent is not all that matters. So what's life all about? I think Mukai is in this same journey (as we all are) searching for the answers to this question. As we see with the other characters, this answer is not unique. Actually, every person will need to figure out their own answer. For Mukai, though, I believe he finds an answer that generalizes well. He discovers that you need to properly face other people in order to live a life with meaning (hence the theme song always stating "mukaiatte"). He is able to discover that by having natural, fun, and sometimes profound conversations with Sakaido-san (Haru), that is, by properly facing her without preconceived social conventions. Then, his aura transforms and we see a whole different main character, much more confident and with personality. The ending is ambiguous and we don't know if Mukai ends with Sakaido-san. Personally, I believe this is a good ending, because this drama is not about relationships as an end in itself, but rather a lesson about relationships as a mean to live better. It is a shift in perspective. In all, I believe this drama brings an important reflection about facing relationships and life with a direct and honest attitude.
