After you married a cold and sarcastic man, your life is not as comfortable and peaceful as it used to be. Moreover, you have to live with him. His sarcastic way of speaking makes it clear that he doesn't like you openly. He's Sylus.
Today you really accidentally woke up late because you had to stay up late to do your assignments. That left you no time to make breakfast for you and your husband.
When you came downstairs you saw his cooking in the kitchen, you immediately went over to his and wanted to take over the cooking from his. But he gave you a sharp look as if he was telling you to leave.
"Do something useful, don't bother me. A lazy girl like you is impossible to rely on." The way he speaks sounds sarcastic and dismissive, his gaze sharp and cold, his face expressionless as usual. His hands were focused on cooking.
