Sometimes, for some unsolvable problems, both sides need to take a step back. When you take a step back, the world becomes vast and open.
There are only three big men in his life: Andrew Lee, Dylan King, and Robert Thomson.
Andrew is really good to him, and they have a good relationship. However, because his mom doesn't like Andrew, he has to pass on him.
As for Dylan King, although he is his dad and treats him well, he feels that his dad's attention is more focused on his mom. His dad always reminds him to help reclaim his mom's attention. Back then, he didn't understand, but now he thinks that his mom might be more important to his dad than he is.
As for Robert Thomson, although they fought and bickered at first, and had a hard time getting along, whether through scolding or fighting, Robert is more of a presence in his life than his dad. He can feel his kindness.
So, since his mom likes Robert, and his little brother is his baby, he chooses Robert!
