They both are based of true events and have political ties. Default also has an A list cast as well and both have time skips regarding the end of the movie. They are both great titles but if you want a similarity to The spy gone north, Default is just as close

From troubled and trauma filled main leads to trying and underestimated female leads these 2 are like enantiomers. The way they both progressed in a slow but peaceful manner and the warm encounters throughout the way is so despicably similar and the best thing in common -murder-. definitely give come and hug me a chance if you enjoyed when the weather is fine. even their titles make a complete sentence.-when the weather is fine, come and hug me-

The cinematography is quite similar and the connection of years between leads along with traumatic experiences that affect their love story throughout the drama. they are independent to their own charms but if you like just between lovers then the smile has left your eyes would be a close hit.
