This series just like TQQ but the children are not related even they are in one family.Even the story not really special but kinda good to watch it,just a bit relate to TQQ.The first episode made me shock a lot when Kotono sharing her love to his brother even she was only 14.Somehow it isn't bad but maybe I think that she isn't enough age to become the bride on this series.Anyways,you can share your review that doesn't impact on everyone's anime experience,the art doing very well and characters have their own benefits and cons that I don't really matter it.I'm just feel like thisseries actually normal.
