OK so a male lead that likes to tease, or lightly bully the one he likes/loves. I'm talking like for attention, or for the reaction cause he thinks its cute. Not like enemy to lovers, or dick male lead bullies the female and falls in love, hana yori dango... But like he likes her so he teases her, or bullies her a little. Nothing too mean please. Bonus if the male lead is weird :P Or kinda childish and you go "wtf man?"
