I'll start by saying I'm not an expert in anything, even less so in cinema so this is just my humble opinion.

This drama started really good and I actually really liked the characters and the story line. I'm usually not a fan of "transmigration" or similar things 'cause most of the time, it's very difficult to write those kind of story "well". In this case, not only is it "transmigration" but it's also a grown up (40+) that goes back into a CHILD'S body.

I honestly thought everything was going pretty well (except the very poor treatment of mental health but because it's a short drama I overlooked it) but the END couldn't have been WORST. How could Dok Pal continue to live in this body ? of course the kid was SUICIDAL so he might not want to come back but like... let's talk about it, let' see what we can do but the fact he STAYED in the body??? what the hell, it make the all point/story/moral of the serie USELESS.
Then they joke about like haha hihi hoho so funny I took someone's LIFE.... no really I can't understand how this was aired.

The last thing, at the very end Dok-Pal says he wants to go on a date... did he suddenly forget he was 40+ ? disgusting.
To make the matter worse I heard it's actually a BL webtoon that they straight washed and in the webtoon, Dok Pal goes out with Se-Kyung which is I think even worse considering the fact he is an adult in a child's body.

well anyway that was my opinion and I couldn't just keep it to myself after being brutally traumatised by that last episode.
