I'm an amateur write so please don't mind me. This story is inspired by Quickly wear the face of the devil, King's game, Who touched my tail, Lovers always on the counterattack, It's not easy wanting to be supporting male lead and etc. This is a BL story as our female protagonist will be the male protagonist in the whole story plot. So do not confuse when you read the first chapter that describes as 'she'. From the arc 1 onward, the protagonist will be male and describe as 'he', no longer 'she'.
