So, i'm gonna be totally honest about what I thought of it. Also, I'm sorry about my mistakes, English is not my first language.
I really wanted to like this one, really. But, unfortunately, I ended up almost hating it.
The artwork is beautiful, the artist is really good at making characters expressions, making them look and feel emotional. That's the best part of the manga. The artwork.
About the characters, the only one I like is Shun. Shun is almost aways feeling down, anxious and nervous, but he always try to do what is best for the people around him. I've lost count how many times
I saw Shun with a terrible expression, that lasted the whole chapter, and no one seemed to care about him.
Mio only seems to care about Shun when they're talking about how good sex feels, and at some point it really got on my nerves. On the first manga he was acceptable, but on this one he's just mean. He never asks how Shun is feeling, never stands by his side. Doesn't care about his boyfriend's traumas and he slaps him when he's breaking down.
The kid is annoying but is just a kid. He wants love, but makes his brother life a living hell whenever possible.
The story seems to be about how Shun suffers every day of his life. He's forced to go back to the place he ran away when he was younger because of homophobia, then he is forced to face a series of past and recent traumas, and no one never seems to give him emotional support. It never feels like he is healing, it's almost the opposite. Almost every chapter he looks miserable.
When things feel like starting to work out something happens and the ends up feeling miserable again. He never really get's to rest. While everyone around him are happy, he is on a corner feeling down. Something that is really present in this story: people happy around him while he feels miserable.
