First of all I have to say that I started to watch this drama only and completely because of Nanon. (Because I truly love that little cutie.)

Overall this drama is good. But I think because this drama revolves around three main characters, sometimes the story gets messy and boring.

Maybe I felt that way because I watched this drama only because of Nanon, and so I was not interested in the story of the other two except for Nanon's story.

So here I'm only talking about the Nanon's character, Tai.

I think if a story shows us a main character with questionable decisions, it should also show us some kind of backstory, which would help us to emphasize that character. So when it comes to Nanon's character (Tai), even though he has some background, I just saw him as a complete jerk. Because there are not enough scenes to let us understand Tai. I mean seriously Tai? Don't you have a brain? Don't you have a heart? No matter how much I loved Nanon, I couldn't help but get angry at this character, Tai ಠ_ಠ. (At some points I thought how good the Tai was before he drank that drink and went back to change the past. Because at that time I felt as if he was a good boy who loved his lover very much. But after coming back from change the past, he acted as a completely different person with no common sense, no heart, and no concern for other people's feelings. I honestly liked him before he turned out to be such a jerk.) So in the end scene, when Earn is forgave Tai, I was so pissed off despite how much I love Nanon. (I mean, it's ok, but how could she forgive him that easily after what he did to her?)

When it comes to their acting, I don't have any complaints. It's just this story that felt confusing at multiple points.
