The drama tells the love story of the dragon male lead who falls in love with the mortal female girl and spends four lifetimes protecting her silently with the hope that one day he will be together with her. The story starts beautifully, like a fairytale. The first 10 episodes focus on the main couple falling in love, and if you are a hopeless romantic you will definitely love this part. Then we have a separation as the mortal girl is reincarnated which is fine at first. Until she reincarnates again, and again. What could have been a sweet and romantic love story turns into a repetitive plot with zero development between the main leads after episode 10.

THE SECOND COUPLE IS WORTH TO SEE:
The love story of the second couple was perfect. "I-love-you-for-a-thousand-years" vibe. They have the perfect organic development and steal the spotlight especially in the second half of the drama. We see them bickering, we see them becoming friendly, we see them falling in love. We see them as the perfect star-crossed lovers. They had the sweetness, the angst, the fire chemistry, the grumpy/sunshine trope, cold man with bubbly woman.

HOW I RECOMMEND TO WATCH THIS:
I'd recommend watching episodes 1-10, then only watch the second couple while skipping the rest, and then finish the story with episodes 29-36. You won't miss anything plot wise because nothing happens in the 2nd and 3rd life. Honestly, if this drama was only 24 episodes with only the 1st and 4th life it would have been perfect for sure. Not that the 2nd and 3rd life are bad, if you watch them as 4 mini dramas they are interesting but the fact that for 17 episodes there is zero relationship development for the 1st couple is just horrible writing.

MUSIC:
I have to specifically mention that I loved the OST and I played the ending song on repeat non-stop. If you drop the drama, at least listen to the ending song as it's perfect.

THE FOUR LIVES:

1st life: ep 1-10 (10 eps)
- FL is an orphan, working as a maid. She is soft hearted and helps animals. This is where the main leads fall in love and it's done really well.

2nd life: ep 11-17 (7 eps)
- FL is hard-working, independent and head-strong. She is bullied by the village’s annoying girl. Honestly nothing much happens and you can totally skip this life (but watch the second couple scenes).

3rd life: ep 18-28 (10 eps)
- FL is a general and the strongest in the army, she is giving Mulan vibes.
- The best villain of the drama is here.
- Great war and fight scenes.
- Feels super draggy with boring side characters. The plot doesn't move forward. Zero development for the main leads. You can totally skip this (but watch the second couple scenes as they are amazing here).

4th life: ep 29-36 (7 eps)
- FL is born into a wuxia sect that fights demons. Everything is revealed here and we have a great final battle (it's low budget but still done well).

OVERALL:
I did enjoy watching this but I'm disappointed because the plot had great potential for the main leads but didn't deliver. I still recommend people to watch this but skip the parts I mentioned above. In terms of acting, I was very pleasantly surprised by the FL. She was phenomenal in playing 4 different characters. ML was a bit stiff but somehow it fitted his character. The second couple were perfect in every way.
