It's because both are the same work, the first one is drama and the second one is special episode of this drama

Both dramas are set in Joseon.
In both the brother of the FML disappears and „comes back“ years later.

Female lead (FL) is dubbed by the same voice actor in both these Xianxia dramas, with both FL characters being "young" and inexperienced. Also, the FL lead wants to "repay a kindness" to ML at the start of both dramas.

Jin Xiu, the King of the Central Heavens, intended to help a little camellia demon become immortal but he became mortal for her in the end.

At the Flower Festival held once every 100 years in the heavenly realm, camellia demon Hong Ning boldly confessed to Jin Xiu her intention to become his queen. When she is told that demons and gods can never be, she takes his advice to heart to cultivate and achieve immortality. Upon her ascension, Hong Ning learns that Jin Xiu is marrying someone else. She resolutely abandons an immortal life to enter the cycle of reincarnation, simply to forget him. Jin Xiu defies fate itself in order for Hong Ning to be reborn. He hopes to repay his debts and protect her for a lifetime. A misunderstanding that cannot be avoided, an identity for which there is no escape; when spring ends, the two meet again. Hong Ning is destined to become Jin Xiu's trial in love.

~~ Adapted from the novel "When Spring Ends, I'll See You Again"

Similarities:
-FL and Ml get separated in their childhood , then reunite later in life with some grudge and things to talk it out
- FL family in both are shitty (one would say TFF FL family is worse) and are the reason why they got separated
- FL and Ml destined together
- yearning component ?

queens who will do everything in order to protect their sons, concubines who love making the queen angry and stepping out of line when they shouldn’t.

you should watch TBNW first as the other one is a special extra epsisode with a light story, fluffy, some kissing and a bit fan-service, there isn't anything surprising but still, it is cute overall, with the same good chemistry between the actors :)

Si Jin similar to The Rise of Ning because of the plot, re-birth, incarnation. Female lead re-birth into a family

If you liked A Dream of Splendor, you might enjoy Les Belles. Both dramas feature determined female leads who rely on their wits and feminine wiles to maneuver tricky situations and improve their lot. Both dramas also feature similar themes of female empowerment and social taboos in a restrictive society, albeit each taking a different approach. Les Belles is a light fluffy romance comedy that lightly pokes fun, while A Dream of Splendor had more serious undertones. Both are aesthetically pleasing and features some artisanal craft. Lin Yun also appears in both dramas.

Healing, sweet, soothing and no thoughts just vibes ^-^
LMLMV: is the drama without the drama
TBT: has tiny angst but it's almost close to being the drama without the drama

Very similar premises (down to some little details lol), ABAAB is definitely on the lighter and sillier side.

There are quite some similarities between these two:
? Both MLs are dentists
? Both MLs fell in love with their patients
? The chemistry of the leads from both shows are cute.
? The supporting characters/couples are awesome and cute

Lots of cuteness and happiness all around. Definitely recommend this drama! ??

Both BL series are about stepbrothers brought together by their parents remarriage. They started out not so friendly with each other, but eventually they developed feelings for one another.

An adaptation of Addicted, but softer. Still step-bro's that fall for each other without knowing, bromance but on the same vibe.

Another Taiwanese series, not step-brothers, but they consider themselves brothers and call each other.
