In the end, Layton compromised.
During those three days, David did not say a single word in front of Dylan.
He was never an altruistic person, but the Miller family claimed that he was created by them and his body and flesh belonged to the Miller Family.
Hence, he would do it just to return them the favor.
After that, he would have nothing to do with the Miller family. He would even pay back everything that he owed to Dylan.
David did not look back at the VIP ward again, just like how he knew there was no turning back for him under his current situation.
Once he made a choice, he couldn't go back on his words.
After a long time, David could still remember his time in the research institute.
In the research institute, he wasn't treated like a human. Instead, he was a beast and was no different from the monkeys that were experimented on.
