Sana and Jihyo's goal is Health and Happiness. In one of their happy sessions, Jihyo notices Sana's tiredness. She thought of taking care more of their health by giving tea.
[This is the cut sexy scene in Chapter 36 of my SaHyo fic, BEST KEPT SECRET. In real life, Sana hated the tea but she was taken care of by Jihyo and/or Jeongyeon. In April 26, 2020--Jeong gave Sana a pack of red ginseng tea, as shared on Twicetagram.]
