If you came for ecchi go somewhere else, this is foremost a comedy manga. And it's alright, not my cup of tea but I'm sure there are people out there who will find it funny.
This is a really great series. I'm a little worried that with how fast things are moving that the central conflict of the plot, whether Leslie will get to stay with her adoptive family or not, will get resolved too quickly and things will become more slice of life. Hopefully the author has a plan.
