The same female lead and similar struggle to win with time. In both stories there's a sweet boy that doesn't know that our femal MC is trying to save him. Both are sweet and funny. In Lovely Runner there's time - travel, while in Extraordinary You the characters are trapped inside a story - however, some of time-travelling elements are also present. Sometimes the male lead forget about his lover and only the girl is the one who can remember the whole story. Both dramas are simple excellent and totally worth your time.

Similarities:

Both are short length historical dramas in which the one ML is in an arranged marriage with the other ML's sister. When she runs away from the wedding, he disguises himself as his sister and marries the FL in her place, a ruse which is quickly discovered by the other ML. The two decide to keep the secret for now.

Both are short stories with mythical being(s) spending a holiday among humans. Both have a similar vibe.

Another Anthology series that others might like if they liked My Universe. It's a series dealing with different couples who get their own episodes, specifically for their pairing.

-Japanese BL
-Center around food/cooking

The notion of family, that familial bonds are not solely defined by blood. Both explores how different individuals can come together to form an unconventional family.

Similarities:
Both shows are romance fantasy/xianxia with aquatic demons (slightly different takes on it) and include the tension & cooperation between different ‘races/tribes’

both have slight love-triangles but the SMLs are mostly silently pining.
ML & SML have a grudging cooperation and evolving friendship, not just over shared love interest but also due to being leaders.

In both couples they are trying to protect their partners and instead are ready to sacrifice themselves
(this includes hiding things from their partners, I just mention it because I know some viewers are sensitive to this and don’t want to watch shows like that, but it’s not unusual for self-sacrificial xianxia plots ^^)


differences:
besides storyline differences, Mirror: a Tale of Twin Cities has slower storytelling and the couple is more on a ‘grown-up & introverted’ vibe while Song Of The Moon main couple is more ‘extroverted & youthful’

Each drama has their weak points, but I still overall enjoyed both and personally appreciate that the ‘love-triangles’ are more handled as ‘grudging & a bit awkward friendships’ between MLs & SMLs :)

concept is same that young female lead is suddenly turned to old
due to different reasons !!!
both are fun to watch and have deep feelings!!
