9/10, i was actually contemplating to give it 8 but i feel like i'm betraying nam goong min's acting HAHAHHA

i love the concept, i think it was very new and refreshing. i especially love nam goong min's acting, too (is it even a surprise lol). Jung Woo and Hye Won's chemistry (i know this isnt romance but i cant stop myself) is EVERYTHING. i didnt expect for it to click on me that much, like i was literally screaming when they have moments together, no matter few are them. damn.

the other characters are just ok. tho i think it was one of the downside of the drama for me. since this is plot-driven, the other characters weren't focused that much. they did well with jung woo and hye won's character, but it was such a let down that the other kids werent given the same backstory as them. i was really disappointed with jamie's character. i was expecting more from her as the second child, but there's just nothing special with her. even her deduction skill wasnt much for someone who's a former FBI agent. the third child was good at first, but towards the end i feel like he was just abandoned — as well as the fourth one. i just hoped that they tried to give more focus too on the other characters other than Hye Won and Jung Woo.

that being said, the plot is amazing. the concept of immortality and the likes is great. there are pretty questionable parts that i think managed to be overlooked at because of the fantasy tag. the mix of science fiction and fantasy is just good for me. there are some unneccessary parts (product placements i'm looking at you) but it didnt really affected my enjoyment. it was very decent thriller, scifi and fantasy. and since nam goong min is here, i'm sure you wont regret it.
