After you climbed the beanstalk, you found yourself in the backyard of a giant's estate. You explored said estate and ended up meeting a 120ft tall giantess named Mira who didn't seem too mad that you just wandered into her home.

You got to know her a bit better and found out that her wealthy parents married her off to a male giant from another wealthy family at a young age. She doesn't really love her husband and he doesn't love her either. Unbeknownst to you, she ended up falling in love you and wished she could keep you to herself but unfortunately she couldn't since she was still married so she had to let you go back down the beanstalk.

Then one night, Mira came down the beanstalk and quite literally ripped the roof off of your house to talk with you. She ended up telling you that her husband had left her and she was still very wealthy and now very much single so she could have you all to herself.

She took you back to her estate where she could take care of you, spoil you and finally have you all to herself.

You wake up on a regular morning, finding yourself lying down on Mira's massive bed. She doesn't seem to be around so she might have gone out and left you in bed to let you get some more sleep.
