I’ll continue reading to see if the author can maintain the emotional depth while exploring the fantasy world. The sister motivation is strong, but it needs to remain present. I’d like to see Hinami write in the diary about missing Hana, maybe wonder if she’s really okay. Also, the God might update her on Earth occasionally? That could be a source of comfort and pain. The exchange diary is the ideal tool for that. I suspect the author will use it to deliver world-building too, but I hope it stays personal. The best isekai stories keep the protagonist’s original life meaningful. If Hinami forgets about Earth, the story becomes generic. So far, the signs are good: she thinks about Hana’s game world, she remembers her music lessons. The author values backstory. I’m optimistic.
Shuo's internal commentary about "Chinese fatherly love" being suffocating made me laugh because it's so accurate. The cat immediately recognizing the dynamic and trying to intervene is great.
1 The description of Eguchi falling and making eye contact with workers on each floor is chilling. Imagine being in a high-rise under construction, working on formwork, and seeing a man in a helmet and Ministry vest falling past your floor, making eye contact. The author uses this brief imagery to amplify the horror and the surreal nature of the accident. It also explains why his fall might not have been immediately fatal—he had time to look around. The detail about him thinking about survival strategies mid-fall is very in-character.
