幸福の遺伝子 (Tankobon Hardcover)

The story seems to challenge traditional ideas of giving and self-interest. Did anyone else feel this made the narrative more layered or conflicted?

It felt like the book was asking big questions about morality and human nature. I'm curious whether these ideas grew organically or were deliberately crafted from the start.

The pacing seemed deliberate, but I wonder if it affected the emotional impact for others or if it allowed for more thoughtful engagement.
