Breakup Probation, A Week (2021)

Both of these dramas revolve around a couple getting into an accident. Afterwards, one of them is sent into the past and tries to stay away from their loved one in order to prevent the accident from happening.

Well, I thought both dramas are kinda similar and have almost the same vibes. In both the main leads are facing relationship problems and are sent back in time for a mission.^^

In both dramas one protagonist goes back to back to past in order to same his or her lovers.
Both have angst moments.Although Blue birthday is a much more thriller focused over youth meanwhile Break Up probation focused over 2 adults.

Pardon my grammertical mistakes
