In order to avoid family marriage, Guan Shuyi had a flash marriage with her uncle Shen Qinyu, who was described by her best friend as "old-fashioned and boring". He is a veteran-turned-capital tycoon in the business world, and he also adopted the orphans of his comrades who died. The two of them got what they needed and lived together, but he always protected the shortcomings - the hospital was framed and he personally supported it, and his ex-boyfriend provoked him to declare his sovereignty in public. One went from being polite and reserved to gradually falling in love, and the other went from being a responsible protector to completely sinking. From contract to sincerity, this marriage began with trade-offs but ended with deep affection.
