Yours, Truly (But Not Really)

Sana is living the life of everyone's dreams.
 
She got the fame, the money, the looks, and, last but not least, an almost perfect husband. When she married Chou Junhui, everything was perfect. She has a better life and is thankful for it.
 
Chou Junhui is an ideal husband. He's caring, handsome, and a workaholic, but he still makes time to talk to his wife and make an effort for her. Sana is indeed lucky to have a husband like Junhui. Who wouldn't feel lucky, right? If you've got a husband like Chou Junhui, everyone will never feel like Sana does because she already has him. Junhui is already and only hers.
 
But when Sana said that her life was perfect, she spoke too soon. Because her "perfect" life with her husband, Junhui, came into a wreck when Junhui's sister, Chou Tzuyu, moved beside their house.
 
And what surprised Sana more were... Junhui's sister is gay, and she has the hots for her.
 
How could Sana handle such a life?
