Both are romance, short and sexy. Both are relatively fluffy. Rinko has more love triangle, but less melodrama.

They have a similar vibe. Mostly sweet and low on angst. Perfect cold man and sweet and naïve female lead.

Same sweet style romance without a lot of angst. Different story but similar tone. Cute and light hearted.

Same fantasy type elements
Male peruses female
Comedy mixed in
Both have the same feel

Koran odyssey is more action packed and intense and love knot is a bit more subdued but still great.

Similar feel with the main leads sticking with each other.
