Okay, let me give you a summary for this.

Two woke up in a Cabin at a forest to discover that they woke up as twins. Girl is suprised that she is now a girl while the guy is Vice versa. 

However, if the boy gets hurt, the girl gets the pain and also vice versa. 

The girl acts like a sassy and narcistic which doesn't match up to her masculine body. The boy acts perverted and tomboyish but is interested in magic after knowing it. However, the girl body excells in physical and spirit infused battle styles while the boy is a spellcaster and hilarity ensues. 

Girl acts like a guy who gets annoyed when girls flirts with him while the guy is disgusted whenever some prince charming saves him and is carried like a princess whose fragile while he can beat them up easily. 

Lastly, the girl pretends she didn't know who swapped them but in truth, she's the one who not only killed them in their past life but also reincarnates then into this world but something failed and they bodyswapped.
