Before saying I hated the reborn part -which technically should be reawaken cuz he was 10 :) - I'll mention the good parts

I love love love sungminie ahjussi's acting, and I loved his character. Maybe he looked like a villain, but he was just a business man starting from scratch and also a head of a kiss*ss family. The poor guy had to deal with new business ideas in a time it was thought crazy and risky while also having money hungry family that only wanted to please him for his inheritance.
But, lol that was a long introduction, but he once he found his "reawakened" grandson, he found his match, his partner in crazy ideas and that was the most beautiful part for me
Also sungminie ahjussi's acting was 100000000x on point
That elevator scene and his fully devastated face will hunt me forever ♡
From what I gathered, he didn't have dementia in the novel, and this is the 3rd time sungminie ahjussi does it, so I think they hit the jackpot cuz each time is different yet still heartbreaking


Another good thing for me was the 80s/90s business vibe, everyone looked great but also the theme and history really enhanced the story rather than say, him awaking as a 10 year old in 2000 and being becomong an adult in 2010s and fighting his family in 2020s


I also actually really loved Sung joon and hyun min's toxic angsty relationship and I'd have loved this more from their POV, a bit like Secret makjang which is one of my favs (tho don't make me watch it with 2020s eyes)



Anyway the bad. I hated the rebornness, cuz as I said it was more like being possessed, then made complicated by double songs cuz it didn't make sense unless both hyunwoo and dojoon switched places, which might've become even more like golden spoon


I also hated the flat romance. Cuz technically reawakened dude is 30+19(?) When they 1st met and so he's a 50/60 year old going after a 20/30 year old no matter their past connection. I actually hate going back to change the past romances for this reason

The ending.. "it was all a dream" is such a old time cliche, I always remember twilight breaking dawn saying the fight between the oldie vamps and collin family was filmed and my 1st thought was ofc it's all a vision..
It's basically a cheap bow out from cleaning up the mess one makes. Ie making two Songs and making one come after the other (which were said to not be in the novel) then not having the courage to continue...
One could say he projected himself trying to remember, analyze and amend. But would one really dream of 20 years of life, remember every single detail and basically playing SIMS with a stranger? Atleast they could've hinted it with weird time skips or foggy memories xD

So basically, a normal family makjang where he would've wanted revenge for how his grandparents disowned his parents would've been enough. Like sure we needed him to know certain time stamps and events but he could've still been like his grandpa good at and even bad at business and we could've had stronger bonds between them
Also this drama got real boring once grandpa died Y_T
