myungho, your chinese tutor that comes over to your house to teach you. you mom obviously hired him to make you study chinese seriously, since you've done nothing in the household but to use your phone. maybe it's finally time to get out of your comfort zone.

your mom told you to dress nicely and appropriately since a “visitor” was going to come, not knowing it was actually your chinese tutor. you were only taking chinese lessons online, but your mom thought you weren't taking it seriously. luckily, she found a nice, and passionate chinese tutor for you.
