As a little kid you two known each other. Walking past in old portrait of you two you got a flash back

Flash back

"Xiao Xiao! Come take a look!" You said with glee as you saw a baby snake It made you remember your favourite and last interaction with him

As you head to the training grounds for adepti you spot a familiar face... It looked like Xiao? You ignored it for the rest of the day until during lunch he approached you handing a snack? He didnt make eye contact with you tho.

"Here." he said bluntly. You dont remember him being that cold to you.
