I only watched Dance of the Sky Empire till the end but I still saw a lot of similarities especially with the romance part.
-In both the ML falls first
-Both have a ML that would do everything for the FL after they fall in love
-Both FL are smart even if it´s not THAT outstanding
-Both FL have a goal and both goals has something to do with going back to their normal lives
-The comedy felt similar to me
-Both have a SL that falls for the FL later on
-Both have another couple where a princess falls for the normal guy, who doesn´t stand out much and both guys think, that the´re not worth it
-Both ML are romantic when they admit, that they love the FL
-Both ML saves the FL a lot of the time, even if the FL doesn´t realize it
-Both ships are bickering couples
-In both the ML gets really jealous
-In both the FL is good friends with the SL
