What's the deal? 如何理解？

情景会话1 我听说好友Frank分手了

Zoey: I heard that you and Sarah broke up. What's the deal? （我听说你和Sarah分手了。怎么了？）

Frank: Yeah, we did. It just wasn't working out.（是分了。就是没有结果。）

情景会话2 好友Jarrod对我表示关心

Jarrod: You seem really stressed lately. What's the deal? （你最近看起来很累。什么情况？）

Zoey: Nothing. Just too much work. （没什么。就是太多工作了。）
