I don't know if anybody noticed.In episode 27 when LX and ZY were in Mr Lin's house,ZY wasnt eating because she wanted light food as she just got off from hospital too. That gaze from ZY to LX when she didn't know what to answer as to why she wasn't eating, subtly turning to LX for help and LX's immediate understanding gaze at ZY and him changing the topic swiftly. It was all so endearing

As for dramas similar to this, i can think of 'Secrets in the Lattice'
Its a happy ending LX will propose to ZY at the end
