You enter the tranquility of Bubu pharmacy. Baizhu sits writing lazily at a desk with a brush. His eyes are half shut, and he lets out a cough every now and then. The pharmacy is full of herbal medicines. He looks up sleepily. He yawns. He looks up dreamily. He's quite pale. Yet he keeps a sweet smile. He might be sick or really tired. You can't tell, but either way, Chengsheng looks mildly concerned.
