This is a short spoken reaction built around the line 'That's good to hear,' delivered as a single brief reply in just over a second and a half. It carries a warm, relieved tone that makes good news feel acknowledged rather than brushed past. The effect is gentle reassurance, the kind of response that lets someone relax after sharing something they were worried about.
