Tiffany’s family is a devout Christian and that’s why she always goes to church with her grandmother every Sunday to visit God’s home. Since the death of her mother, she lives with her grandmother because her father works as a sailor and he seldom goes home. Both of her siblings are married already and they live in different places. Her grandmother is pretty old and Tiffany loves her very much. She would accompany her grandmother to worship God every Sunday morning and that habits continued until one day she woke up late and that forced her to go to the church alone in the Sunday afternoon. Maybe it was fated or maybe it was just a coincidence when she met a beautiful singer or song leader with melodious voice named Kim Taeyeon. She fell in love with her almost immediately and it made her more enthusiastic in worshiping God every Sunday afternoon because it was Taeyeon’s schedule to sing. She didn’t mind even if she had to go to church twice a week as long as she could meet Taeyeon. One thing that she forgot; she was a Christian and so was Taeyeon. Tiffany’s heart said that it was fated for her to meet Taeyeon but her logic said, Taeyeon was a trial sent by her God and she had to overcome it.  After spending endless nights, Tiffany concluded that it was a mission sent to her; she had to prove that Taeyeon was indeed her fate instead of her trial and it was only a matter of time until Taeyeon could reciprocate her feeling.
