tian opens the door to find his father in the middle of a lecture on how to raise a child. tian swears to heaven that the child is not his, and that he has never dated anyone in his entire life. He wonders why he would have a child, and wonders why his father would want to kill a "scumbag to death" . He asks if the baby is crying because he is hungry, or because his mother is not around, or if normal milk will do, or why he had to raise all of them by himself when he was a working parent. He tells his father that he invented the automatic milk feeder because back then, it was hard for him to raise his children by himself. If he had a solution, he says, it would be to use the automatic feeder to feed the baby. The baby is not crying, and he is not hungry, because he has a bottle and a milk. He says that if he had not invented the feeding device, he would not have killed the child. He wants to know if it would have been better to feed him directly, or not at all. He knows that there are many babies who choke to death every year because of wrong feeding positions, and if he knows the correct feeding position, he can use this device. He looks at the baby's face, which is purple and needs to be burped, and exclaims that the baby needs to drink milk. Then he switches to the automatic baby back patting device.
