So, back to the story, Felix, the teen who was cold, had changed after Karl's confession about his bad experience. He must have overcome his jealousy to make the troubled one feel better because he himself knew the pain.
Asher felt the duke was so innocent and kind.
He deserves all the happiness in the world.
So, their somewhat messed up pasts had made them friends with time. Even though he still couldn't get close to Felix as much as Lucas, he patiently waited and treated Felix better. With time, both of them got more closer with Lucas's help and after Anne appeared in the picture, they got even closer.
Karl, the rich prince often sent gifts and things for Anne and Felix.
Even though visiting them often wasn't possible for Karl, he did his best to show them his presence through gifts or letters.
Eventually, time made them who they are today.
