Oops has a recurring day while perfect husband has a slightly different paranormal event going on… both have very different endings starting with the same theme
Other than the recurring day, the series are quite different. But give them both a try, you may enjoy both.
Both have relationship troubles but qot doesn’t have the supernatural stuff of oops. The basic plot is similar in both, one is a 16 ep kdrama while the other is a 14 ep Chinese web series
Both have a similar theme, oops has some otherworldly stuff like repeating day, but otherwise they have the relationship fixing plot
Both have a similar relationship fixing theme…. One is more comedic and the other is more serious, but the point is the same
Both have the tangentially similar theme of fixing an ailing relationship…. Recommend to watch the other if you’ve liked the first whichever it is
Even though derailment has a more serious note to it, and the story is quite different, both seem to evoke the emotions…. Derailment has some memory logic to it and oops is about a time travel game….. I would recommend to watch the other if you’ve watched the first
Similar break up - reconcile theme with the leads trying to understand each other. Familiar wife has more depth and logic, but comparable amount of magic/time travel is involved….
Both series have relationship troubles and time travel. Oops! Has a recurring day, but otherwise the same theme is followed
