How recently did Rin finish achieving her revenge? It doesn't sound like she's moved on from it or settled into something else. If that's why she came to this place, Mizu doesn't know what to tell her. It's a fresh start, but it both isn't something she expects to last forever and only pauses what waits for her. Is it worth it?

That's not Mizu's problem. Rin followed the fox spirit, and she's here. It is what it is.

Thankfully, the young woman pulls herself together. That makes Mizu more comfortable again. Yes, enough crying! "We both expressed apology," Mizu states, "That should satisfy the conditions. How long has it been? We might need to wait out the four hours."

Unless the fox spirit does something for people who complete it in under four hours.
