I completely agree with brid. I really liked the original idea and how the personal and professional lives of each started to flow into each other, but what I'm disliking more and more is any real depth to the characters. They're seeming to be more and more just products of their situations . The further I read into this story, the more the characters get flattened out - opposite what I want to see.
Reading brid's comment reminded me of Souichirou's original depth which I had completely forgotten existed at one point. To the point I've read, he's become a simple-minded character only capable of protecting or thinking of Kaname, and every now and again acknowledging Masato's existence. As for Kaname, he's struggling to let go of his past, and somewhat getting over it, but there's NOTHING else. He only has his past. That, and the ability to become the perfect homemaker. As far as I know, he doesn't have any goals or dreams for the future. As for his relationship with Masato, it seems to have completely disappeared despite their previous living together and extremely intimate relationship. And because of Kaname's and Souichirou's closeness, Masato seems to be completely separated from them (except when required to fill in the 'brother moments') and his story is becoming more about the drama around the film world. At this point it almost feels like the mangaka should just drop him as a character and give him his own story (or I'd like to say that if he had enough depth for it) because he doesn't really serve a purpose to the protagonist anymore other than aiding him when Souichirou needs a mature opinion on a matter.
So, for a plot which screams to be character-driven (what decisions will they make regarding the circumstances they were thrown in, how will their relationships develop further, how will they grow to become a family, how will it change their characters, etc...), the characters are completely falling flat. As a result, as it currently stands for me, I wouldn't recommend it, but I'll continue to keep reading for a little while longer (I have a high tolerance for bad/boring storytelling after all).
