Both dramas have a main couple with a very healthy, supportive relationship, despite the existence of an age gap.

Both are age-gap dramas where the fl is older and the ml is younger.
In both shows, the male lead chases the female lead first (according to the tags)

Both dramas include gaming
Both main leads are pursuing their dreams while falling in love

The female lead is older than male lead in both stories.
In both dramas Male lead chases the female lead first.
Both are romantic dramas with great chemistry between the leads.
Cute and funny side characters in both dramas.
If you like one drama you will like the other.

P.S: *cough* Steamy scenes in both dramas *cough* :p

Both dramas include the career singing
ML struggles in his singing career like FL from LC
Both dramas include a love triangle
Both ML confess first

Both show the difficulties of fame

Both have lots of authentic care, understanding, romance and supportive male lead (in love scenery, the ML is supportive from the beginning)

Both lack major unrealistic drama / really evil antagonist

In both they meet in a game and the male lead is a very good gamer. In love scenery the female lead is famous but in Double love the female lead wants to be famous. They are both cute fluffy dramas I highly recommend.
