@Piex Granny is mad.
@daywithoutgames Guy already agreed to pay two hundred thousand for Fonshen but Granny is still angry because of the past. I've said it before in a previous chapter and I will say it again. It was not about money.
@Mivas The sick woman was Mao Mao's mother (and she knows). She lost her virginity to Rakan, then did questionable things as she descended into insanity (she sliced/cut Mao Mao's pinky) which also eventually caused her health to decline. Since he was technically the primary culprit for all this, Granny kicked his ass/"banned" him and prevented them from meeting. (He was perma banned in the original WN and she died. This is probably pity reboot)
Mei Mei is crying because she apparently liked Rakan as well.
@Esasaeriri Because she died in the WN before they could reunite.
