After breaking up with his wife 8 years ago, Jose has been raising his son Hyeonbin by himself. Hyeonbin used to be always talking to his dad but now he's in adolescence. He's always playing and on the phone with his friends, and he has no problem talking to auntie. However, he just doesn't answer to his dad. What is the reason? It's because of Jose's frustrating Korean skills. Jose can't understand difficult Korean words so Hyeonbin has to explain to him repeatedly. As he got to adolescence, he became more frustrated with this. Jose has always been friendly and nice to Hyeonbin to make up for mom's absence. Thus Jose is sad to see such a change in Hyeonbin.
