Although Andrew's smile seemed tender, for Kalifa it was the smile of the devil, because she thought that Andrew was already plotting how to make her suffer the moment she broke the promise, so her body trembled involuntarily.
Andrew didn't understand Kalifa's adverse reaction, but knowing that she wasn't comfortable, he pulled away from her and stroked her head as if comforting a little girl, which confused Kalifa, but she still enjoyed the sensation.
It was strange to her how Andrew could make her tremble with fear and the next second melt with affection. Make no mistake, she doesn't feel the slightest bit of love for Andrew, at least not romantically, she just feels safe, like she's under the protection of an older brother.
Despite the strange feeling, Kalifa did not dislike it. Andrew stopped stroking her after a while and walked away from her, letting her resume her work, but before leaving, he warned her to sleep well today.
