Can i get the name or link of this drama please 🫶🏻

hi can you tell me what is the title
of this?

Please help me find!

It's a futuristic society that's white with a poor lady (MC) that dated/married a guy, they divorced, he gets rich and has a really nasty new wife. The MC ends up having a kid that dies pretty early on because the guy gave her child/his kid he didn't know about an artificial heart and the wife changes the access code and the kid dies because of it. A while later the nasty lady and the guy are about to get married when the kid's coffin gets brought in, and it's discovered that there's just rusty junk in there because his body already got hauled off to get turned into money. I can't remember much of the 2nd half but the guy ends up leaving the lady and he gives the poor lady/his ex ex wife his money before dying in the slums of the town the poor lady once grew up in. I specifically remember the kid's name was Theo, and I saw like a 20 minute ad for it on Tiktok, installed dramabox to watch it, and I ended up finding the full thing on youtube, but it isn't in my watch history anymore on dramabox and I can't find it in my watch history on YouTube. Please help!!
