How is that other teacher gonna see Eunyung has an eyepatch over his eye and scold him for ignoring his teacher??? Don't you think the eyepatch is why he skipped school? If it was any other student they would've assumed that's why he skipped.
Also that other teacher pisses me off. YOU CAN'T GIVE UP ON KIDS!!! No one gave up on you which is why you succeeded! He literally has to go home to his parents who failed him! You got to ho home to your grandma who always supported you!!!
