   Summary

   “Oh.” Jeongin’s expression cleared in understanding. “This is a pregnancy thing.”

   Seungmin glared. “We don’t know if I’m pregnant.”

   Jeongin frowned. “But Minho-hyung said—“

   “Minho-hyung doesn’t know anything,” Seungmin cut in. “Seriously, why does everyone take his word as gospel? Is he god or something?”

   Jeongin grinned. “He might as well be. When has he ever been wrong?”

   OR

   The Sequel to 1+1 = 3 where Seungmin and Changbin navigate the ups and downs of pregnancy together.
