I have no idea how successful this would be in the real world, but I imagine some work to make Song Li seem more human might well be able to shift the dial a bit . . .
That said . . . this is effectively confirming the CP/ship, and I'm not sure whether Hu LuoLuo realises that? Pretty sure Zhao Huan gets it, and probably thinks it's a good idea at this point to just recognise it and move on, but it doesn't seem like LuoLuo realises . . .
Pretty sure Song Li sees this as something pretty close to an outright (and very public) confession, though - she's not planning on resorting to violence when she gets home, she's got something more . . . intimate . . . planned.
Well, maybe a bit of violence - how else will she know if her LuoLuo likes a bit of playful spanking?
