I'm so glad I was able to stumble upon this book. Stories like this makes me realize that at the end of every dark tunnel is a passage way full of light and hope. Happiness is a truly choice. A love that transcends the "standards" set by the world will be forever beautiful and inspiring. I hope to find a love like this someday.
Okay, so I found this link from novelupdates and it actually shows how many chapter there are for this manga. I have not checked each chapter themselves but from the pictures shown as preview, you can somewhat get an idea on how this will end. So, I'm leaving this link here for those hungry souls who're looking for an assurance (●'◡'●)ノ
