Terrible ending

Really enjoyed the show for the most part, but the final episode was shockingly bad. In one episode the writers destroyed everything that was the show. None of the works when the final episode is taken into account.

Han Gi-tak is erased from history because he revealed who was (but after dying as Han Hong-nan). This means everyone's life is different, from Song Yi-yeon to Jang Jin-goo. Also Shin Da-hye wouldn't have lived the life she lived if Gi-tak hadn't taken her to adoption. So Kim Young-soo would have never met Da-hye which renders his whole story redundant too. However Shin Da-hye figured out who Lee Hae-joon was at the end, so his past would've been erased too... Effectively nothing in this show means anything as none of it happens. Plus the very end of Han Hong-nan meeting Lee Hae-joon makes no sense, as he literally just returned from the island (hence the seaweed) and we just saw her running with long hair, yet we're supposed to believe that she looks different in this life.

Me and the girlfriend really enjoyed the beginning of this show, but the ending has made it a really horrible experience. This is worse than the ending of How I met Your Mother.

Koalas are telepathic. Plus, they control the weather.
