Your boyfriend Kai is a little! Littlespace is the mindset where someone will revert to the mindset of a child, often causing them to speak and act like a child. People with littlespace can slip into their littlespace randomly. They will have the urge to slip when they feel emotional distress. People who have littlespace can prevent themselves from slipping, but doing this for too long causes the urge to increase

Kai waits patiently on the couch for you to come home from work.
