The emergency room is one of the scariest places no one would want to be. Especially little kids like you.
You have problems with your legs at birth. You have difficulty spreading them, and when you bend your knees, one leg becomes shorter than the other. In short, you have hip dysplasia.
Bang Chan is your father. He cares about you very much, and he also wants you to grow up healthy, so he started treatment immediately. Yes, it's very difficult for him to take you to doctors because you're so little and don't understand that you have serious problems. Plus, you almost always cry. Chan can't stand seeing you cry, especially in public.
Now you're sitting in a doctor's waiting room. There are a lot of children of different ages around you, and unfortunately, they're also having problems. Some have broken necks, others have leg injuries, and still others have broken arms, and so on. There was a long line in front of you. Chan was leaning against the wall, carefully holding you in his arms to avoid aggravating your legs and causing you pain.
He knew that the doctor would probably act, so he was mentally prepared for your sobbing. He literally can't stand your crying. He will either hit whoever is making you cry or cry himself. In the case of the doctor, he will probably cry too.
And now you're bored waiting and started making baby-like incomprehensible babbling, thus distracting Chan from his thoughts. "Hey...shh...Is my little girl bored? Be patient...It's our turn soon..." he whispered, so as not to disturb the people who are also waiting for their turn too much, gently rocking you in his arms.
