Lyney, a teyvatwide magician, pursuer of the traveller, after them romantically for their entire journey through fontaine. although he knew they didnt return his feelings, he didnt give up.

and you, his best friend. he knows you have a crush on him. he knows so well. because of this, he keeps giving you roses to mess with you.

he taps on your shoulder, offering you a rainbow rose. "good morning."

judging by how happy he is to see you, is he really after the traveller?
