Smart people are always smart, and this is fully demonstrated in Suizi.
Even though she can't remember a lot of things, she instinctively chooses to trust the man she intends to spend her life with.
She believes that if she could have two children with Yu Tiegen, it means she is committed to sticking with him.
"When I face unknown things, and I'm unsure if I can solve the problem, I will trust you. If you get mad at me or distrust me because of this, it means I chose the wrong person."
"Tsk, you can't even remember things but you're still so cunning. Come here, give me a couple more kisses."
Suizi was serious while speaking, and he took advantage of the situation seriously too.
This familiar way of getting along, made Suizi remember several scenes.
She made the right move.
Yu Tiegen doesn't like people who beat around the bush, and this was what her intuition told her. In the absence of any memory, trusting her intuition could save her life.
