The drama gives a realistic view on marriage and what happens when two people stop communicating and being considerate. Cha Joo Hyuk is selfish, self-centered, and completely unaware (or refuses to acknowledge) that his weaponized incompetence triggers his wife's temper. He dreams of a better life without her until he is given an opportunity to travel back in time to change his outcome.

The first 12 episodes have consistently good pacing and fluid storytelling. Cha Joo Hyuk wakes up married to his beautiful and rich first love until he meets Seo Woo Jin again. I enjoyed the use of flashbacks showing just enough of Joo Hyuk and Woo Jin's relationship and how in love they were before marriage, which plays a big part in his character development. The story switches between comedy and melodrama as the main couple gets to know each other again. The writers portray Joo Hyuk feelings of guilt and regret rather well as he realizes the gravity of his mistake and what he lost.

Woo Jin is clever, spunky, and has a hilarious sense of humor. I really love her characterization. Thankfully, the writers avoid the cliche portrayal of a messy and childish heroine, and create a well-rounded adult who can be serious and funny. Her and Joo Hyuk have very good chemistry and slowly begin to re-connect. Even secondary characters are fun. The drama gives them just enough focus not to overwhelm the viewer or take the attention away from the main couple.

The last 4 episodes undo everything I loved about the drama. After confessing his mistake to Woo Jin, Joo Hyuk is desperate, full of regret and longing. This is when the story should've started to wrap up. But, the writers force us to sit through 4 more episodes of Woo Jin relentlessly pursuing Joo Hyuk to reconcile. Joo Hyuk's behavior is completely contrary to what he wants as he goes out of his way to avoid her and regresses back to the self-centered jerk he was at the beginning. Instead of giving his redemption arc a logical conclusion, the writers turn him into a spineless coward refusing to make any effort to be a better man and husband. The main couple's explosive chemistry completely fizzles out with Joo Hyuk's vacant stares and Woo Jin's continuous begging. At that point, it is hard to root for them or even care if they stay together. Moreover, the drama gives too many filler scenes to the secondary characters. I say watch episodes 1-12 and skim through the last 4 just to get to the happy ending.
