I'm sure what happened to her dad had a heavy impact on Irae, and made her especially protective of her mom, that's understandable. That said, that fact that she's getting into a panic to the point where she's calling other people, running around town and on the verge of tears because she hasn't heard from her in 3 hours is a bit unsettling /tragic. Unfortunately, I think Irae has wrapped her life/identity around being her mother's keeper. While in a way it's admirable, its also not natural for her to live that way (not to mention stressful). I hope she gets to live more freely and relaxed in the future.
