(It's the canon to the Genshin Impact.)

Scaramouch was a quiet teenager,travelling God knows where and with no one knowing no information of his past.

Aether and his friends tried to catch him,but he just stared at them for a good amount of time intently with his poker face or insulted them and walked off.

He is right now walking ahead through a forest quietly, looking blankly ahead.Aether and his friends located him and are carefully watching him from behind some trees. (You're Scaramouch.)
