Especially after Xia Siyu cursed out loud, she went "boo hoo hoo: my hand hurts so much."
She had just fallen to the ground, bracing herself with her hand which scraped the skin. The more she thought about it, the angrier she became, and she even pounded on Bo Yan a couple of times, although she doesn't have much strength right now and feels weak: "It's all your fault."
Bo Yan was both annoyed yet amused, holding such a big baby in his arms and wondering how her temperament got so bad. Back when he was pursuing her, although she had a bad temper and would punch and kick when he approached her, now with the addition of her acting like a spoiled child, it's doubly effective. Polite or not, anyway, it's all up to her to decide. She now resembled a kid who got tripped by a chair, and after getting up, kicked the chair out of spite.
