Su Zhinian pretended to knock on Song Qingchun's bedroom door twice before pushing it open and walking in. The sound of water in the bathroom provided the perfect cover to his movement. The girl in the shower was humming happily, and she didn't even hear him walk in.
Su Zhinian walked to the bathroom door and knocked on it. After a while, the sound of water inside stopped, and Song Qingchun called out, "Who is it?"
"Tingting, it's me."
"Huh?" Through the bathroom door, Su Zhinian could hear Song Qingchun walking toward him barefooted. "Didn't you say you're going home? Why did you turn back?"
"I remembered that I had something to give father on the way home, so I came back…" After a pause, Su Zhinian added, "…You'd better finish showering first lest you catch a cold. We can talk after you're done."
