Wei Shen's family seems to be the same as other people's families, but they also seem to be different.
Other people's family is a family of three, and so is theirs.
One father and one mother, this is someone else's home.
Two fathers and one son, this is the Wei Shen family.
Wei Shen has two nominal fathers.
Concept: Life is rough, but savoring it carefully is also warm.
