This is just hyper unrealistic. There's no one who would suddenly become this emotionally aware. If it looks like that, it's just they had always been that person, they just forced it down.
From childhood to adulthood, there's no empathy, people even put arguments like "How he can understand love when he's given none?" Suddenly turns out empathetic?
