Sana woke up unexpectedly from a slight movement in bed. In the early morning twilight, she turned her head and looked over to find Mina spooning Dahyun beside her. They had both sidled up against Sana in their sleep, with Dahyun pressed into Sana's side as Mina held Dahyun from behind; a "Dahyun sandwich", as Dahyun often liked to call it.
