AUTHOR'S NOTE:
Hi, this isn't a chapter update. I just want to announce that Big Brother Kasamatsu is being rewritten at the moment. So no more chapters will be updated here.
Please check my profile for the new version: Big Brother Yukio, if you still wish to read the fluffy kyodai relationship. But be warned that after uploading/updating five to seven chapters in the new version, Big Brother Kasamatsu will be deleted.
Anyways, I also want to say how thankful I am of all the support and the reviews I've recieved for the past...how long this fanfic has been going on. Your words and support has always given me lots of motivation about certain aspects of my writing, especially my creativity. I severely lack in that area honestly (its the part of the exams back in high school I fail the most, lol).
Thank you for all the support, and I hope you can continue to support me and other writers out there!
