Bo Yan looked up at the bathroom; the bathroom's red light was on, clearly indicating that Xia Siyu was still inside.
For people like them, having two phones is normal. One is for work, and one is for daily use. The one Xia Siyu left behind was obviously for work. The phone she took to the bathroom was her daily phone. Additionally, to conveniently use an alias to browse Weibo or check WeChat messages, generally everyone registers two accounts, one being their real identity and the other an alias. Just like Xia Siyu's real account and her gossip account, just like Bo Yan's main account and "Shengxia Yanyu."
The message Qin Baizhou was replying to was also her real identity WeChat account; it's likely she had logged out of her alias account.
