Comment by Gyeolloml on Pure Love Operation - Chapter 81

I've read a comment of someone  a month ago (I don't remember when) saying that eunhyuk might can't hear properly might be true! 'cause before when soo ae became close with eunhyuk she was told to collect notes in class and she called him to collect his notes and he didn't answer her, he was only using one headphone. One of her classmate said that he doesn't answer anyone or hear anyone when he is studying cause he's so focused on studying 
Now seeing his left ear bleeding.. he might actually can't hear properly from his left ear  :<
