From chapter 7 of A Chui's tale

Andrew tries to help Katie get over her lack of confidence, but the first day doesn't go as well as they planned. Katie tries to runaway that night, fearful that she will hurt him again the next day, but finds that Andrew is again one step ahead of her and prevents her from leaving. Going back to the spare bedroom that Andrew kindly lets her use, she soon drifts off and Andrew pops in later that night to she if she is alright and tucks her in, speaking softly to her that what happened that afternoon was not her fault.
