It's a very heartwarming manga, and the emotional beats do hit hard, but I need to discuss something about this manga that has been bothering me a lot since I read it. Giant spoiler wall incoming.
I'm really not a fan of how Kyouko acted in this story, and I don't think the mangaka really handled a character dealing with the trauma of rape and sexual assault well.
So early on in the manga, we see a hint of an intimate scene with Touma and Kyouka, a page of just their arms, fingers interlocked on a bed. I thought it was weird at the time because the timing of it was so off, and Kyouko is really still not okay in this part of the story, so I thought "Oh, this must be a little vision of what's to come, very nice." since the characters acted completely straight like absolutely nothing happened between them at all.
But then it happened again. And again.
So you realize that they've been fucking this entire time, and basically one chapter later, they drop the reveal that Kyouko was the survivor of a brutal sexual assault case. This event obviously completely destroyed her, and you see the aftermath of it everywhere. But that's not the issue for me, the issue is that she hasn't found any way to cope with her trauma in any meaningful or healthy way, can barely hold herself together in public, her self-image is completely destroyed, is unkempt, lives in a stye because she has no motivation to even wake up in the morning, let alone clean, but somehow has the confidence to pretty much immediately put herself back out there and have sex with a childhood friend? Like, are you kidding me?
Looking back at some of the panels in this manga earlier on into the story, it really actually does seems like Zyugoya is trying to glorify and fetishize sexual assault and the horrific, lifelong scars it leaves on one's psyche, with shots of her boobs, or her in revealing pajamas, little things like that.
I am NOT trying to accuse Zyugoya of this or that, since he (she?) has written other manga that deals with similar themes where this particular aspect of Broken Friend is completely absent (Crybaby Neighbor). I wholly believe this is just a case of them liking big tiddy sad girls (me too) and just failed to fully analyze potential implications of the story when they drew Kyouko's body front-and-center. Regardless, it still really rubbed me the wrong way.
I don't know who will see this and want to read it, (certainly not Zyugoya), but whatever, here you go.
