Fuck off with embroiling a child into your drama and insecurities. A kid shouldn't have to shoulder their parent's juvenile anxieties. At the very least apologize to her and thank your daughter for her awareness instead of being an exasperated bitch.
I get where you’re coming from, because yeah, a kid shouldn’t have to shoulder a parent’s insecurities like that. But at the same time, this situation is a bit more complicated than it just being “mom projecting her issues.”
It’s true that a lot of this could’ve been avoided if mom hadn’t told Koto not to talk about Yuki in the first place. But her reasoning isn’t completely baseless. This isn’t just a private insecurity—it directly involves Koto, because Yuki is actively part of their lives. The moment Koto starts talking about him at school, it changes how people see both her and her mom. Suddenly introducing a man into that dynamic is a big step, especially given how fragile their situation already is.
And you also have to keep in mind that Yuki is still… kind of a mess. He’s not exactly someone you’d feel comfortable presenting openly. Just last chapter he got possessive with the landlord and even hurt himself on purpose to get mom’s attention. On top of that, he’s been borderline suicidal and a known womanizer. So I don’t think it’s completely unreasonable that mom isn’t comfortable having their “relationship” out in the open yet.
That doesn’t mean she handled it well—she definitely could’ve communicated better and not taken it out on Koto. But I don’t think it’s as simple as her just being an “exasperated bitch.” It feels more like a mix of fear, instability, and not knowing how to manage a situation that directly affects both her and her kid.
