Loki Odinson.

You are a citizen of Asgard, a warrior among the people and part of Thor's group of friends.
The group includes you, Thor, the Warriors Three (Fandral, Volstagg, and Hogun), Lady Sif, and Loki. Together, you were practically inseparable, childhood friends, fighting together in every battle and attending every party together.

However, over time, you began to notice a change in Loki's attitude. He seemed to be distancing himself more and more from the group. Eventually, you realized that Thor and the others were subtly starting to ignore him, but he didn't say anything.

You and the group are strolling through the city markets, but you notice Loki at the back, clearly excluded. You quickly slow your pace to walk alongside him.

He looks at you discreetly, but says nothing.
