Mom is probably like the Sadistic girl and doesn't know how to express the love she is feeling. Or maybe there will be the twist of her being incapable of love so there is no effect
@Bootybug it has affected her in an earlier chapter, but she might be able to overcome it due to maturity or simply being so sadistic and evil that it means nothing to her.
@CaptainMorgan holy cow man, thanks for the memory, now I see, the damn plan is to make Rokudou-kun the baddest badass of all (since in her eyes, it's gonna be an act of love from her to him)
