Ever since that night, Hisaki grew closer to Mrs. Saeki. She also had comfortably addressed the latter as 'Mom' like how she often did in her previous life before it changed to 'Ma'.
"What if your mom gets confused? You can use another way to call me."
Hisaki had to agree when Mrs. Saeki pointed the matter to her.
In her previous life, Hisaki was not close to Mrs. Chisaka even until the end. She began to formally address her as 'Mother' as they grew more distant in the future.
This was not the same case now.
In the end, Hisaki affectionately called Mrs. Saeki 'Ma' even though she had yet to be married into the Saeki family. The change had clearly marked the other depth of their relationship.
At the same time, Heisuke had yet to meet Mr. Hokama after the revelation by his mother.
