Paying Life Debts (BL)

Autumn woke up in a weird place because her surroundings were all in white. Right then a cute childish word spoke up.
"Good day, host! Nice to meet you! I'm system number 911 at your service."
...
"Host, did you know that your accident has killed 9 people on spot and make dying with you?"
....
"Now you have to pay your debt to them for ruining their lives. As you have made 9 people dying, you will be sent to 9 different worlds too make it up for them and live their lives to maximum happiness and peaceful life that they could ever wish for. If they have any regrets or any wishes, you must complete it without failure."

However, she never thought that she had to live as a man in every world. At first, she had a difficult to adapt but afterward, she found that lived as a man is easier than a woman because she did not need to worry about that every month. Plus she could look at every handsome man as she pleased without worry that they would misunderstand her like when she was a woman.


Author's Note:
The image is not mine. 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'.
