I just watched the whole story and my favourite part was that in the part-2 where Cheong suddenly spoke in front of others and told that the weather is too hot. Also I want the story to be continued because the last episode part-20 made me cry alot because she was leaving and erasing everyone's memories and even she tried to erase the little grl's memory but she couldn't and I was just crying the whole day after watching episode 20 it was just the most emotional movie ever seen
