Chen seems like a free spirit, he’d be totally up for it. He’d purposely troll and make you blush from embarrassment. He’d use this opportunity to get in as much skinship as possible. Lots of back hugs and kisses on the cheek and finger tips while calling you “master”. He’d tease you in a ual way just to see you blush and stutter. Something like giving you a back hug, pressed tightly against you and whispering in your ear, “Can you feel my heart beating master?”. Stuff like that but he wouldn’t go any further than that though.
