Fang will obviously be the type to complain and complain about why women suffer the most during their period. Later complains, why women does the pregnancy thingy. Complains that they carry the baby in 9 months. Complains that childbirth hurts as hell. Complains being a mom is so hard than getting a job. Complains that she has to do all the house work where in reality we only just wanted to portray Fang as the grumpy complaining sassy girl where the author accidentally starts talking nonsense that isn't relevant or somehow connected to the current topic where everything got out of hand...

Then Fang later complains men should also suffer the same way as women.

Kaizo being the big brother, always have to stick to his loud annoying sister by giving her whatever she wants especially red carrot donuts and going to the store to buy her napkins (he was forced by his mother XD)
