It never crossed my mind that it could have been Tatsuya... and Kazu and he are brothers!!! OmG!!! But actually I'm glad it ended like this, and that they all stayed friends although they had to face a lot of trouble. Especially the last scenes were awesome, my favourite scene is the one at the end. It felt like you were closing a circle, it started with the necklace and ended with it.

Thank you so much for writing this~ :D
