Life's dilemmas

In this timeline: Xia Guo finds her arrogant mother trapped in a situation (in her own way) that is also humiliating. And Xia Guo is found on the street, drunk, but Yu Jian finds her and brings her a moment of tranquility and relaxation. And Yu Jian's family is also Xia Guo's family.
Yu Jian and his sister have a fight. His sister perseveres in defending the life she has chosen alongside her foreign husband.
In the other timeline: She is humiliated at work, and is forced to make a choice (which she has resisted until now), somewhat unconsciously to protect her relationship with Yu Jian.
