Yeah I get it that this type of story isn't for everyone, especially those who seek fluffy and light-hearted stories. And for those who doesn't get the struggles the characters dealt with, we must always take into consideration the time this piece was published, it's been 9 years. Of course, sexuality was very black-and-white back then, it was either you're gay or you're not.
I absolutely agree with you too. Additionally, I also like when the story portrays that all of the characters, one way or another, which really brings the story close to the readers' heart.
This sequel just overdid its prequel and I love it! The rating is so underrated for this gold manga but I guess not everyone can appreciate this wonderful story. Again, this series is not for the snowflakes and overly-optimistic people in terms of love and it should be as second to its prequel or main story.
