Everyone who studied with Shuhua and Soojin bet that one day they would date but to their surprise Soojin met a boy named Junseo, fell in love, dated him throughout her college years and got married as soon as she graduated. While Soojin started a family Shuhua had casual flings over the years, she became a veterinarian and the cool aunt of Soojin's children, who appeared from time to time with gifts. The friendship between them strengthened over the years, Shuhua helped with the kids whenever she could and became Soojin's shoulder to cry on when her marriage began to struggle. Soojin tried to save their marriage but the truth is they had fallen out of love, they loved each other but weren’t in love with each other anymore and they both agreed that Soobin and Hayun deserved to grow up with happy parents

Junseo moved to an apartment and the kids slept there during the weekends, at first it was hard for Soojin to get used to the situation, she needed to rediscover herself since she had created a life around Junseo, a life that no longer existed  but she had support from her parents and especially from Shuhua, they were close friends but after Soojin's divorce Shuhua became more present in her life.

-Glad we are finally on the same page, I've been in love with you since the first time you lent me your notebook in science class

They started dating but only told the children a few months later, at first Soobin and Hayun were upset when they learned that their mother was dating cause deep inside they had hope that their parents would get back together but over time they realized that Shuhua made their mother happy. It wasn't just Soojin who was moving on, Junseo had met a woman named Anne and intended to introduce her to the kids too, a new family was forming, a blended one

Shuhua and Soojin had been dating for three years when Shuhua moved in with them, at first she was afraid of disturbing Soojin's relationship with her children, she had built a good relationship with Hayun and Soobin over the years but living together was a completely
