I've skimmed through those chapters too. It's too hard going for me. The way I see it, the little kid is a victim of human trafficking and is being tied up most of the time, and given illicit drugs against his will, until he's an addict. He's probably being sexually molested too. The blonde kid isn't the one who originally imprisoned him, but is an active participant and is actively imprisoning him and drugging him too.
Yes, the trafficked kid gets away and is found by the seme's dad, who helps him to escape and looks after him from there. This is obviously all a flashback.
I'm not disappointed, lol. Either way, the blonde guy's obsession with the uke and his need for absolute control over him is really icky and dehumanising. I've looked at the raws, and he is absolutely sexually obsessed with the uke and jealous of his relationship with the seme, but I don't want to get into more spoiler territory
I think there's implied abuse. Just because the artist/author chose not to draw it and chose to use sub-text instead, it doesn't mean it's not there.
FYI, in case it helps you, here's Cambridge Dictionary's definition of "sorry to disappoint you":
"to fail to satisfy someone or their hopes, wishes, etc., or to make someone feel unhappy".

Can't find any sources for your own personal definition, not even in the Urban Dictionary.
I had to skip those chapters with him as a kid, i don't want to read them, not sure i can handle.
The blonde kid drugged him and that's it? And he escapes?
