I enjoyed watching this show really very very much! This made me really into Woo Do-hwan. The chemistry between them is crazy.

Story :
So, the story was amazing.
Hae-Jo (Chae Seung-Hyeok) and Jo Jae-mi, a couple, well, who broke up a few years ago. Hae-Jo finding out he had a serious brain condition, sees her after those years, also having a day with bad luck. (I definitely don't want to spoil the rest of the story)
Hae-Jo's motto was really special and catchy. So, the title is just about this motto, by Hae-Jo, "Don't set a destination, only then you can't be lost" just meaning Never set a destination, Just go where your life tells you to go.

Acting/Cast : All I gotta say is they were amazing.
I wanna talk abt Kkari, such a funny goofball, always going into problems. Every time I saw him, I found myself laughing.

I think the music was nothing too special, but still, it was agreeable ig.

Chemistry is what I want to talk about the most. Like, they look so good together, I can say, Hae-Jo and Jo Jae-mi look good together but I can also say Lee Yoo-mi and Woo Do-hwan look good together! They just carried fine and good.

Conclusion : My main point of view is that
This was so realistic.
The chemistry was fire!

*Spoiler*
So, this, being a sad ending was my one and only dislike about this drama. But even though it was a sad ending, I love how it was so realistic, instead of like a stupid miracle happening, like, he was suffering from a serious brain problem, and it would really be unbelievable like, if he lived. I loved how they made it realistic, however, it was really sorrow to me.
