[Oh Kratos. He just doesn't get it, does he?]

Don't be. ...She's been sent home three times already, only to return here a while later. She never remembers, either.

[Having Martel here means he's living in constant fear that she'll be sent away again. Having her here means he's constantly worrying something terrible will happen to her. Then, when she does go home, he's left wondering how long it'll be before she returns to Luceti once more. It just can't work like this. As much as he loves her, Yuan can't really look her in the eyes anymore because he's just so goddamn afraid.]
