Matthew's mood changed after knowing Sophia would study abroad for her Master's Degree. He felt like history was repeating itself.
Yuri left Matthew for her studies. And now Sophia would also leave to pursue her Master's Degree.
He was also upset because Sophia didn't mention anything to him. Zhen-Zhen seemed to know about this news first.
The five couples continued their bond until 5:00 pm. They left so that Tristan and Zhen-Zhen would be able to rest. The twins were also sleeping in their nursery room.
Matthew and Sophia were the ones who left last as Matthew continued talking with Tristan while Sophia stayed with Zhen-Zhen. Matthew and Tristan dropped by the nursery room first, checking the twins. While they were watching the sleeping figures of the two babies, Tristan confronted him as he noticed his silence.
"Are you okay? Why do you look so troubled? Is it because of Sophia?" Tristan asked him.
