it wasn't just the date, the times Sakura has appeared and even the girls has realized that...Sorry but, this manga just lost its chance to be praised by making her turn down the guy because of a date she had with Yuu more than a year ago (manga timeline)
At this point i'm hate reading
Sakura with Yuu has the greatest chemistry so far.I like Niko the best of the three sisters, but Sakura feels like a better match for Yuu
