Julie's Translations:

Kento probably says something like "Are you serious?" but she's not sure what he's saying.

Rowen: What else is there to do?

Kento: Fine! (and some other things)

Rowen: Really?? (and some other things)

(Rowen obviously looses here)

Rowen: Okay, time for round two!

Kento: No round two!
