This is different types of drama. No connection between old drama Eternal Love. And this drama follow the real novel.

Story: Story is too deep. The novel has promising story.
Acting: overall good. Acting is developing carecter by carecter. Leading role are so good at acting.
OST/Music/Song: Too good. All musics are heart touching.❤️ Better than Enternal love.
VFX, graphics, animation all are good. Better than Eternal love. The fox is quite good. And fox animation is so natural.

Colour gradient too good. This is so charming for eyes. Totally eye catching.
Story, acting, VFX, graphics all over first class. I think leading role will be acting 3 different types carecter. I must say that this pillow book is so good. And I cannot wait for next episodes.
