"You can really cook?" 

Heaven smiled, stopping from cutting the onion as she gazed at her son. Sebastian perched across the counter where she was preparing the ingredients she needed to make dinner.

"Of course! It's a shame I haven't made you a single meal, but back then, I would starve if I don't cook for myself," she shared with a smile, resuming her activity as she added, "It's a bonus that I like cooking — or maybe the process of how these ingredients turn into something."

Sebastian studied the slight smile plastered on his mother's face. "Why would you starve if you don't cook for yourself? Don't you have someone to do it for you?"

"There was, but 90% of them tried to poison—" Heaven almost bit her tongue as she realized what she was about to say. "I mean, there was someone. My dad. But I can't keep relying on him. Moreover, I liked cooking. So even when I was working, I do it to relieve my stress."
