Cool female

Female lead is super cool mad scientist, her creations are amazing, and she crossdresses as a guy in her own novel (transfer world)
Male lead handsome

Female lead is really adorable and wins over her fathers cold heart (FATHER, DAUGHTER BONDING IS BEAUTIFUL), BUT only for him to LOSE his memories and attempt to end her. Female lead is strong and continues to fight (its a tear jerker)

hopefully her father will remember her soon and when he does he is probably going to feel very guilty
I super reccomend this, it is really good

Femal lead has AMAZING medical skills (≧▽≦) - (she is reincarnated and instead of being empress, she wants to be a doctor), she is very intelligent and calm in most situations.
The male lead soon falls in love and her father and brother are very doting
