"And I want to trust him... And I want him to trust me"
Your attitude of not telling him anything, constant assumptions of his attitude and behaviors, and just how passive you've been about anything regarding your relationship (chocolate making was the twin sisters' idea, introducing naruse was the families idea, every date was naruse's idea) and god damn even when you try to be active, like with the bento, you flaked out at the end and had to be pushed by other people.
Granted naruse also sometimes doesn't tell her stuff, i.e. the cold, but damn, it just feels like she hasn't ever considered how naruse would feel, when she's always complaining about how naruse doesn't care about her feelings.
