There's something about a seme who doesn't smile, doesn't show his emotions, or/and is just plain unbothered by life. Bonus points if the uke is a ball of joy. The release of serotonin I get when they finally do smile (not smirk!!!)? Unmatchable. Said semes are usually blunt, may hurt people's feelings, and don't know what white lies are, but hey, at least they're not people pleasers. God bless.
