I think this manga does a better job than most at depicting possible consequences of CSA, and it was respectful of the mangaka to not linger on the act itself (like others do, to the point where it comes across as exploitative), rather focusing on Tou's struggle with it. Most of the story is from Shizuka's point of view, but the reader also gets insight into Tou's life and reactions, that Shizuka isn't privy to.
Unfortunately, there are two parts that bring down the manga for me. The first is the photographer's comments about Tou having something alluring that entices others...right after hinting that Tou may have been a victim of CSA. The essence of it was "I'm not gay, but...", which creeped me out. I get what it was going for, but it could've been phrased better and Shizuka should've called him out on it.
The second part is the subplot with Shizuka's university friends, because it's rushed and comes across as a pretext to have Shizuka "rescue" Tou, and for them to separate once again so that Shizuka can chase after him. There should've been an entire scene, not just a panel, of Shizuka's friends apologizing to Tou, because what they did (and were planning to do) was awful.
Was it absolutely necessary to include Tou being assaulted again? As underdeveloped as Shizuka's friends are, and as quickly as their part of the subplot was resolved, it would've been better if they were left out entirely.
Having said that, I am thankful for this manga existing. It's not perfect, but it's miles ahead of other works that only use CSA as a superficial "personality flavor". I like that a confession and getting together don't magically "fix" trauma. I like Tou's "People have the right not to forgive" statement, and the growth he goes through that eventually allows him to choose whom to forgive.
