"Alright," Yang Ruxin acquiesced easily. She indeed needed to practice her calligraphy properly, after all there were no simplified characters or ballpoint pens here, and if she ever went outside, being unable to write would be a disadvantage.
"Then tomorrow..."
"I'll come over in the morning," Yang Ruxin glanced at Gu Qingheng, "it's taxing on the eyes at night." The light from oil lamps and candles was too dim, and prolonged exposure could lead to nearsightedness. Moreover, the atmosphere at night seemed inherently more ambiguous; there's a saying about the allure of looking at a beauty under the light, and under candlelight, Gu Qingheng appeared even more irresistibly stunning. She didn't want to challenge her self-control daily.
After all, if one starts thinking of someone as a brother, but then can't hold back from pouncing on them, wouldn't that turn one gay?
She still needed to maintain her self-respect!
