Does this drama have a Happy Ending?

Notes

Time Travel always has this big confusion of what is going on. This drama was not as confusing as the person going through time had to learn all the information the same time that we did, that actually helped.

There is also the question ‘What if we change something in the past, what happens in the future?’ which is actually answered by sudden new memories showing up that help in the case after things being planted in the past.

Trigger for murder cases, that do show some pictures and indicate the murders when they happen, as well as some other violence. Which is to be expected for a crime drama.

All in all happy ending. The murderer is caught, the past it changed so the future changes too, a lot the loneliness and trauma didn’t happen because of it.
