I don't see why he couldn't simply tell Xia Ning what's going on with Mei Ruo except for stupid manufactured drama reasons. Also, the excuse for why she isn't in a hospital is laughable unless she paid the doctor off to say that.
@BZo1480 I mean Mei Rou clearly been unwell for a long time and they have just been ignoring it, who tf gets obsessed with someone for drunkenly mistaking you for someone else once?
