I finally caught up with manga (chapter 34), I read all the comments and saw the divisive ratings and decided to give it a ago. SO this comment is for those who didn't read it yet and decided to come here and check what people say.
I mean, how bad can it be to get average grade of 6 here?
Suffice it to say, it was a wild ride. Obvious incest tag aside (which was a hook up for most people I believe) the story is a roller-coaster of twists after twists. Most 1 star grade you see is regarding the chapters 13 to 19 where quite the bombshell was dropped and needless to say it filtered out tourists.
But then, it starts to get better story-wise. Almost wholesome experience. And then chapter 33 came along and man... I watched "I Want to Love You Till Your Dying Day" and "Love Unseen Beneath the Clear Night Sky" recent anime episodes and they emotionally destroyed me. I was not prepared for chapters 33 and 34, they tore up what was left of my fragile heart.
I did read some of the LN spoilers for ending but I am still interested in seeing how will this go forward. So, to me at least, this manga is worth checking it. Just for the roller-coaster ride of emotions it will deliver.
