Vol 4: Ch 192 – Misunderstanding
Afterward, another doctor happened to pass by in the room and then heard a very familiar voice. A voice that he missed for 3 years and that woman his wife who suddenly disappear and then the two start arguing because of some misunderstanding before she disappears but Na as the spoiled brat didn't listen to her husband and so they start fighting with words only. Both Rei and Tae just listening to their family quarrels because both of them are outsiders so just they keep quiet. The two don't want to interfere or eavesdropping but there's no other choice since the family members are quarreling in front of them or maybe they forgot their existence at all. Even the family members are quarreling, they just exchange words and words but not shouting since they're in a public place even though they own the hospital they know that's a public place and indeed they're all professionals.
