Both have a similar college romance vibe. The ML in both the dramas are more on the cold and detached side and are somewhat standoffish at first with the FL. The FL is very lively in both the drams and have a similar vibe.

Similar since in this drama they get divorced dude to lack of communication and in Go back couple they are having problems due to lack of communication as well. Have similar marriage vibes and relationship with second lead in a way.
