another time-travel romance drama where a teenage girl travels back in time and falls in love with not a king but a young lord in this one. it is also adorable like this drama and the story is well-written.

It's been a while since I watched RIABB so I don't really remember the details but there was a wedding.
And then the leads did cohabitate together for a while.
And there's also the discovering one's passion part.

Both start with the cancellation of a marriage.
Both have the cohabitation trope.
Yugure ni, Te wo Tsunagu is kind of like a modernized Long Vacation.

Both of these are high school romance dramas.
They both become close because they are desk mates.

• bubbly female lead & "cold" male lead

In both shows, the female leads "fool" the male leads by using false identities.
Both dramas are romantic comedies with sweet female leads and calm & understanding male leads.
