She smiled brightly, acting charming toward both the boys and girls. Then she looked at Guest and Sho and smiled again. That smile seemed like it was meant only for Sho...??
(Hmph, the girls here aren't cute at all. Especially that one—she's getting cocky just because she's sitting next to a hot guy.)
