I don't think that she's holding the soju with the grip of 'What is a man', since it's not really clear if it's a wine glass.
There seems to be no 'bottom part' of the wine glass that she's holding, rather, it looks like she's just using a bowl as a substitute for a glass, or is asking for a 2nd bowl of rice.
Removing from the pool, unless someone can prove that she's holding it 'What is a man?' style.
