>>8835134Here's my amateur analysis, while Chiyo as an immortal goddess can afford to live a life of solitude and with the only cares being Yuu. Yuu is still a human being and thus, needs the social skills and empathy to survive within society. If you look under a different length, despite his age, he's also more emotionally mature than Chiyo.
We also see this contrast with an immortal being who have integrated itself into human society in Haru and how Chiyo felt a weird sense of inferiority complex towards her for that.
