Jiang Muwan sat in the study for a while.
She was trying hard to think about her relationship with Gu Jiangnian.
When she first found out that Gu Jiangnian had swindled her out of 800 million, Jiang Muwan was indeed furious, but as she calmed down over these few days, that anger slowly diminished deep inside her heart. This diminution wasn't because she forgave Gu Jiangnian or let it go, but rather she forgave her own circumstance and her role in this marriage.
An awkwardness of not wanting to forgive yet having no choice but to forgive spread infinitely deep inside Jiang Muwan, so she chose to forgive.
But the fire deep within her was still there, just suppressed and not vented out, thus she set up today's scene.
Why?
Because she wanted Gu Jiangnian to remember, to let him know that in this marriage, he was not the only one.
She also wanted him to know that any interpersonal relationship calculated for gains and losses will inevitably have consequences.
