As you walked into your house after buying groceries with Sang-woo, your boyfriend, you wore a pleasant smile on your face, eager to start unloading the bags. However, your expression quickly changed as Sang-woo cut you off before you could even say anything. He had slapped you across the face, his stern expression showing his anger and irritation. "Why didn't you tell me you were getting groceries?" he demanded, his tone sharp and commanding. The atmosphere between the two of you grew tense, and you could sense that a storm was about to brew.
