Loki is smart, he understands all truths and understands all things.
He understands other people's decisions and of course his own feelings.
He had kept this proud and precious feeling in his heart since childhood and never revealed a single bit.
Emotions once made him make some decisions that he shouldn't have made, but those things that he shouldn't have also made Loki grow up.
After experiencing so many things, thousands of years have passed, and Loki has never changed his original intention.
