Unfortunately, Deku's freedom was short lived

After all life can't be good to him at any point that's ridiculous

So as he is proceeded to be told that they would return him to his family, expecting him to be happy, as soon as he is in a physically stable enough condition which considering the regeneration quirk  (although they don't know that) that was forced upon him unfortunately wasn't very long at all

So he tries to force down his healing time as long as he can trying to prolong the peace before he would be pushed into the belly of the beast but in the end all his best attempts are futile as he is stood in emotionally as his 'loving parents hug him perposely pressing on his known wounds (that there not aware have healed fully or about his crazy high pain tolerance and he would like to keep it that way) while smiley (fake) looking police officers are unaware of the situation they are putting the kid in

Time skip:

The car ride back was deadly silent but deku would have taken that uncomfortable silence over the beating he got when he returned 'home'

That he took without flinching, a single scream or noise uttered he just sat there 'without showing any emotion' glaring at a small crack in the wall refusing to give his birth giver or sperm donor the satisfaction of hearing him scream and knowing the hurt him (which wasn't very hard considering his 'punishments' he got at the league for his very existence)

occasionally instead of staring at the wall he would merely glare into there tormenters eyes to show he is not afraid nor will he back down from his beliefs as an attempt to embed his face into there memory so they can never forget there sins and the use of memory and/ or lie detector quirks/ invention (although lie detectors aren't reliable) could be used as prove there actions against him as they are less likely to forget his face when he comes back even stronger than before and shows them that they messed with the wrong person and it will come back to bite them later.

Because before Izuku was sold his parents supposedly claimed he would be home schooled but clearly don't care enough to actually spend any time or resorces on him that could be spent drinking (if only they had that mindset when it came to the abuse) Izuku took it upon himself to insure he got a good education so Izuku would travel to the library (which is going to be fairly near the school) and by using his computer that he earned through using his analytical skills to work anonymously analysing quirks for those in need (after a in depth background check being done on them, and when something especially bad comes up he would send the information to the police effectively catching there eyes and working closely with the police along as helping those in need in order to effectively control there quirk and occasionally hero's in training or just helping clear up misconceptions about people's quirks

He also caught the hero's eyes and becoming a source of information for them as well (any suggestions of what name he should do all this under) and becoming Nezu's chess buddy as he is apparently the only one who can beat him
