Tang Yuchan had been sitting there, quite curious about what they were going to discuss, something she had never heard about before. After sitting there for a while without hearing them talk about any serious matters, she just stayed put. However, they then said they wanted to go somewhere else to talk, which seemed to imply that they found this place too noisy.
But if they were to go somewhere else, wouldn't she lose the chance to take advantage of this dim environment to do some naughty things? That way, she could quickly bridge the gap in their shared memories. This thought made Tang Yuchan very distressed. Couldn't they just not go somewhere else? Sure, it's noisy, but they could just lean in closer to talk.
