Both are female centric dramas, although To Dear Myself is a lot heavier on the heart/they take a more realistic and less idealized viewpoint on life.

The both have a similar plot where the male lead has a sick grandparent who wants to see him fall in love and marry a girl so they end up having a contract marriage.

Both deal with fangirling. In Record of Youth the female lead starts a relationship with the object of her fangirling wherein Her Private Life, the female lead becomes closely intertwined.

Same creator. A spin off of Gameboys, Some of the cast such as the male leads would take cameo in the show. It also has similar themes as love during pandemic and the use of video calls and social media as interaction between the characters.

Both dramas have a ML who is sickly, weak but highly intelligent and masterminds of everything, at the same time somewhat charismatic. Both FL are good at fighting and becomes intangle with ML due to some past who needs to be investigated. Both have similar humour and quirks, but The Moon Brightens for You is more comedy than Love in Between.

Both dramas have exaggerating/over the top humor and Ahn Se Ha is in both of them as a supporting character.

From the first episode of The Penthouse alone, I can already make parallels. Rich families living in an exclusive property, two students who are competing for one goal, a highly-esteemed teacher, and so on.

Faith is my favorite Korean drama featuring time travel. These two dramas share similar concept of time travel, which a modern man in Mr Queen, a modern woman in Faith travelled back to the historical era.

The same thing between these two dramas is that a man's soul is entering into a woman's body. Both seems fun and hilarious.

Both are South Korean dramas, similar in that it features a modern person who time-travelled to the past. In Moon lovers, it is Goryeo Dynasty. In Mr Queen, it is Joseon Dynasty. Another difference is that Mr Queen features a man in a woman's body and Moon lovers was a girl residing in another girl's body.

Similar points:
*The FL is from other planet to Earth
*lnterspecies Romance
*Supernatural Powers
*Hidden Identity

Both dramas' MLs travel back to the past and more precisely to their high school years, and both dramas actually use this trope to portray a huge, inspirational, life-changing personal development.

-FL is independent, smart, down to earth
-FL & ML have history (different types but still)
-has moments of comedy and more serious parts too (although WDL has more heavy parts)
-there is a kind of childish FSL
