My fav is Drift. He is a spot on traditional Asian Dad
TM and I like how he learn to open up to his minicons/pupils/kids bit by bit. It feels personal because that’s how the parents from two generations ago to nowadays parents about my age have evolved.
I don’t have a least favorite. No characters are that annoying in RID2015.
My favorite ship is Drift/Fracture. Long term rivals is my kink. And they are both single dads XD
