Switch Girl!!, Himouto! Umaru-chan Recommendations
It's funny how some characters can maintain their dual personalities. For both series, there's a main female protagonist that can "switch" on and off as if they become a totally different person. If you enjoy fiction that balances a character at different locations (home/school), then these two manga series are differently for you. Just note that Switch Girl focuses more on drama while Himouto! Umaru-chan adapts more of a slice of life/comedy hybrid.
