[He keeps a smile on his face and his tone is light-hearted as hers, or as much as he can get. There's, however, a tiny hint of cold steel under it.]

Depends on what kind of regret you're looking for. Regret for allowing her that much time? Yes. Regret for seeing her burned and running away? She made it hard for me to feel that way. Especially when I warned her.

[Ikki knows his faults, he won't deny them. But as far as he's concerned, Selphie's main problem with him was how he just didn't fit her image of an ideal boyfriend. How he didn't match the expectations she built of him. And how he didn't want to have sex with her, regardless of the reason as to why he felt that way. And it's pretty hard to feel regret for being a jerk to someone who made him feel as if he had to be tamed or something.]

You don't have to convince me any further that you're a smart girl. Though it's nice to hear you doing so.

[The hint of icy steel is gone from his tone, leaving a more normal and warm one. He chuckles softly, clearly amused by her.]
