Feels like we're making some progress now, but the question response to a question feels annoyingly coy to me. Just answer the question honestly, and say how you really feel.
If you are speaking of the last bit of dialogue in the chapter, Seungha is quite clearly having trouble recovering from what Chaeyeon just said and it’s a wonder the conversation is still going. It looks like she is trying not to tear up and cry.
As far as telling her how she really feels, Seungha has been really bold already. If saying she is interested hasn’t worked so far, I am curious what she is going to say that WILL get through to Chaeyeon. But first Chaeyeon is going to need to explain more unless Tima has Seungha read minds next chapter (because in so many years since what Seungha seems to remember is not the milk or apples, but her big gay crush and probably needs a refresher course on how fourth grade level flirting can be incompetent).
I understand this, I'm just venting some frustration because her being roundabout has led to her crush of many years thinking she hates her. I'm sure I'll come around if she explains herself next chapter or so, but right now I feel like despite her having a difficult time this is an important conversation, and she needs to finally make her intentions clear.
