FL2
The exclusive maid of FL1 (sent to replace her for "marriage night" / MC chose to not do it at that time, bc of being a good man wanting consent)
Weak. No strength.
High EQ
Ruthless
Love both MC and FL1 (master)
Was given plum-blossom hidden-weapon by MC to protect herself (the small thing that can shower enemy of needles)
prologue
= (old) mc angry at world. Despite trying everything, becoming global famous doc, saving SO MANY PEOPLE, paying a nurse, or winning a PEACE nobel price he couldnt get a wife that could love him (crippled)
Short time but very profound
"WHY" mc so cynical, so mature(old), doesnt care use any method. And why obsession to point of madness about "family"
