Gal mother situation gets worse as the curse is lethal when it gets to the brain, she thought to have more time as it was in the ower body but it started to spread in a weird way, I think getting to her lungs, MC decides to help her, they have daily session with massive amount of exp being given.
One day she gets a report of the petrification having spread even more wildly, they have a even more intimate session that leaves her drenched and convulsing.
She goes to the dungeon with her normal clothes and poor gear or normal rentable stuff, she goes on a solo expedition and return 3-7 days later, with some injuries and her uniform tattered, but with the peach (together with some other stuff she found and another miracle fruit she mistook for the peach).
They run to the hospital and give it to the mother that rcovers almost istantly, big happy cry moment.
After that MC and Gal have a nice talk, she then leaves the story for the following chapters, wanting to stay close to the her mother for rehabilitation and family time, reasonable, is even so that MC can pass to the next girl, like when it passed from "tutorial" one armed sensei.
Gal level at the end of the "sessions" was around 200-250.
The girl after Gal will be the idol, that is MC crush he feared to have killed, her hair turned white for the shock, MC had dumped a shitton of exp in her, her parents thought she was rape dgiven how much her level raised and took her away of school and moved away, not letting her go out, not knowing what happened that was a reasonable reaction, she became a idol so that MC would try to contact her, not realizing he never recognized her, they meet by chance, she is EXTREMELY into MC and the unique pleasure he can give her.
