Ani-Imo Vol. 6 (manga)

There's no straddling the fence now--Youta has gone all the way over, head over heels, to embracing his feelings for Hikaru. But now that he's willing to see Hikaru not as his sister but as a lover, Hikaru seems to have slammed on the brakes! No kissing, no touching, and no......

Could it be that Hikaru is the one unsure of her feelings now? Or is she gearing up to take their relationship in an entirely new direction...?!
