Xefros is a shy troll compared to his friend Dammek. He may be able to stand in front of people and sing, but in reality he has stage fright, it takes him a while to get to singing.
But after he meets his flush crush he will sing his heart out for them, on and off stage, but he is still shy even to the point that his face turns turns a deep burgundy when he takes their hand to hold.
While writing for a new song for the band he would think of his crush and his hand would start writing on its own.
When he confesses to his crush he would sing in a in a tone that only his crush can hear, he would hold their hands with his forehead pressed against theirs as he sings his love confession.
When his crush is sick he would wrap them up in a blanket and hold them as he watches their favorite movies with them,even the really bad ones, and make them soup so they can get better faster.
He is good at hiding his anger unlike Dammek, he would hold it in till he was able to write it down into a song, he thinks writing is better than striking.
When him and his crush are laying down in his bed he would wrap his arm around his crush as they lay there and listen to music, both soon falling asleep.
