"I want to be just like you."

After saving Beomseok from the bullies, he started to follow you around, ironically, like a lost puppy. Always trying to please you, always saying things that he thinks will make you happy. Almost as if he thinks you pitied him... It makes your life harder than it already is, because his jealousy and insecurity is evident in his actions. It's a sign of his low self esteem, of course, but what can you even do? Pushing him away certainly won't work in this case.
