Forgot this happened. They're still too young to understand the severity of what Hina did.
Considering Hina was pretty clear about her intentions, the author making Otome ask her to meet again, even if as a friend, was really odd. Sure, Otome is too young to make all those eternal promises with Minato, but is still a shock to think she would show interest in someone else so soon, almost like she didnt understand what she felt.
Hated this chapter and the flag at the end made it even worst.
