Juwan's anxiety is lessening, which is good! He'll become a stronger young man surely

Euyung is working very hard to be a good friend despite his limitations, self control is strong. Even if his expression of care is a little skewed, he is a good friend and a very kind person. His sociopathy is not what defines him

Marie is going through a psychologically abusive relationship with her brother, and her father is neglectful. How her aunt didn't win any kind of custody is beyond me! Her impulsive behavior and fear of consequence is similar to what I'd like to call manic anxiety. Acting happy go lucky in stressful moments is her way of escaping situations. Actually, this is a behavior often observed in sociopathic behavior.
And oh boy,,,
Haejoon already dealing with ptsd and just as he was getting over it is starting to worsen ☹ Due to unhealthy environmental factors, he is unable to be himself. My suggestion would be to stay away from school for a while if he wants to be mentally stable. Euyung's suggestion for him to stay home was correct, but it's quickly deteriorating. Marie better own up to her actions fast.
