With his friends like Nino, Adrien's use of the Peacock Miraculous could make them feel a bit left out at first. They are used to the 'normal' Adrien, and this new side of him with different powers could seem a bit alien. However, as they see him using the powers for good, they might become more interested and start to support him, but there could still be moments of misunderstanding. For example, if Adrien has to disappear suddenly to deal with a sentimonster, his friends might think he's avoiding them.
A plot twist might be that the Peacock Miraculous starts to have an unexpected effect on Adrien's personality. Maybe it makes him more assertive in a way that his friends find a bit strange at first. He could start to make decisions that are out of character for him, like taking more risks in battles, which could lead to both positive and negative consequences. He might also develop a connection with the Miraculous that makes it difficult for others to use it when he's around.
One possible plot could be that Adrien stumbles upon the Peacock Miraculous by accident while exploring an old attic in his mansion. He then has to figure out what it is and how to keep it safe from Hawk Moth.
In a fanfiction, Adrien's mom might have used the Peacock Miraculous to create something special.

The story could then explore how Adrien discovers this connection as he grows older and becomes more involved in the Miraculous world.
