Keiko's mother's surgery was not difficult; it was a CSF leak, so all that was needed was to confirm the leak point through a nasal endoscope examination and then proceed with a single-nostril transsphenoidal approach for the treatment, which would effectively cure the condition.
As for the cost of the surgery, it was not very high. Jounouchi Hiromi had already inquired about it. When Keiko's family's financial situation was still adequate, her mother had purchased medical insurance. Such traumatic injuries caused by traffic accidents fell within the scope of medical insurance compensation. Therefore, Keiko's mother's treatment costs were not high to begin with, and with Jounouchi Hiromi agreeing to advance the treatment costs, the issue did not add to the financial burden of Keiko's family.
Of course, whether owing Jounouchi Hiromi such a large debt of gratitude would bring psychological pressure to Keiko was beyond Jounouchi Hiromi's control.
