The over-all vibes of both shows are quite different, but if you're into supernatural beings who are also detectives, maybe check this one out.

Both deal with a police inhestigation to find a serial killer. The villain in both dramas are really twisted and seem unstoppable. The actors playing villain do an excellent job in both dramas.
The female lead in eaxh drama is bright and male lead is more reserved and introverted.
In TGWSS the female lead has a painful past wheread in Flower of evil it is the male lead who suffered in his past.
Overall both dramas are addicting. Flower of evil is more heavy and the other one is more light.

Coming of age story about 2 characters finding a relationship where they least expect it, and with who they least expected it.

dr. koto synopsis first few line remind me romantic dr. kim

It is a remake of this drama. Same story but much better CGI and acting. It is basically a much better quality version of this drama.

Eternal love of dream is also a fantasy story about the heavenly realm,demon realm and the mortal realm.Both the dramas have heavenly emperors.the idea of God is war( Mo Yuan in ELOD and chu xuanji in LAR)is also common.

Love, love, love this show. Like Love O2O the couple stay true to each other regardless of misunderstandings or other peoples interference. The female lead is also a lot animated than in Love O20. The male lead still has that inner strength/aloof persona but he mellows out as the show progresses. While the show is set in the gaming industry it doesn’t focus on the gaming side but the business end. This is the perfect anti-stress romantic drama. It is definitely on my repeatable list.

Very similar world with magic and dragons.

The main similarities are:

Male and Female Lead are singers.
ML unable to cultivate since childhood.
Met female lead when younger.
FL is saintess with great power, but seems aloof. (she's new to acting, however I'd say her performance is about the same as this FL)
Destiny and unlocking levels and great schools and tournaments with rankings.
Powerful evil clan, that provides conflict, but is defeated many times.

My Favorite

Male lead that has a (deep friendship/symbiotic relationship/Master and Servant like relationship) with a non-human female support.

I don't remember any kissing in this, but there is affection. The actors are new.

The bad boy image of the 4th prince in Moon Livers is similar to Qinyue. Both characters are dark and are competing against the “white knight” to win the heart of the girl.

Both dramas have the same leads as the main couple. Also both dramas have a contract relationship as part of the story theme.

Prequel to the YYY special. Focused more on the relationship between all the people in the apartment rather than just Nott and Pun.

Both are Filipino dramas the deal with The challenges of maintaining relationships during the pandemic. Both use a video chat format where the actors are not together.

The female leads are the same. Love better than immortality is a fantasy, romance series of tencent video. A girl who went to the past for experiences love. And there she fall in love with two different persons who are like black and white. In order to the rules when she open her eyes which person she see first he will be her destiny.

Both main characters are born with powers that they don't see and eventually through the help of people around them and the academy they learn about their strength and follow through with the fight against the evil

Both of these are about Ancient powers where the main character both are seen as week and throughout training from a academy learn more about their power and uncover it becoming stronger on the way.
