MC really is a chameleon of kinks for his partners lol
He's got the dom side down pat with Mi-ri, who's a (very) tsundere maso sub with a praise kink
Tbh he's pretty dom-y with the other women as well, just not quite as much as with Mi-ri haha
And now he's got So-yeon down bad with his usual good boy side; wouldn't be surprised if she wants him to call her noona or even mommy (though I feel like that last one might be a stretch)
