Female first and male second:
"Ah Chao, they don't know that today is also my birthday."
"It's okay, Nuannuan, I will spend your birthdays with you from now on."
Female one and male one:
"I hate you"
"I know"
"Let me go"
"Be good"
The first female and second male are as warm as the first male is cruel.
(Alas, I have no choice but to change the introduction and the chapter names purely for the sake of good looks. This article is just to satisfy my love of torture.)
