Just recently. It suits me, right? [The genuine smile turns into a more charming one, with a touch of his usual mischievous manner.] Now nobody has any excuse for getting us mixed up.

[He laughs, and reaches out to ruffle Haruhi's hair.] Of course not! Who wouldn't want us around? It'd get so boring! [He won't tell her, but the gratefulness is for always remembering to consider Kaoru along with him. It makes him feel okay about spending time with her; because she understands them.]
