emo了 is casual internet language for suddenly feeling low, melancholy, or sentimental.
emo了 gives a sudden low mood a little distance without denying it. A song, an old photo, or a familiar place disappearing can tilt the evening, and the borrowed label lets the speaker admit the feeling without turning the chat into a diagnosis.
The register is casual; the feeling does not have to be. That is why a good response often follows the actual reason—sit with it, change the plan, or ask what happened—rather than joking that the speaker will be fine in five minutes.

我刚路过以前那家书店，门口贴着“明天最后一天”。
Wǒ gāng lùguò yǐqián nà jiā shūdiàn, ménkǒu tiēzhe “míngtiān zuìhòu yì tiān.”
“I just passed our old bookshop. There’s a sign saying, “Last day tomorrow.””

就是想到这个，突然有点emo了。
Jiùshì xiǎngdào zhège, tūrán yǒudiǎn emo le.
“That’s exactly what got me. I suddenly feel a little emo.”

那明天下班去坐最后一次。
Nà míngtiān xiàbān qù zuò zuìhòu yí cì.
“Then let’s go sit there one last time after work tomorrow.”
Wen’s mood drops for a specific reason: the bookshop where they used to study is closing. emo了 names the wistfulness, and Di changes tomorrow’s plan so they can say goodbye.
