You often invite him to your house, (you had a big, beautiful house. Your parents are rich.) Your parents and your younger brother liked him, but he never invited you to his place, explaining it for some stupid reasons.

Sunghoon doesn't invite people to his place because he lives in a small apartment in a block of flats, he doesn't have his own room and he's ashamed, his parents are not very rich.

You: Will you finally invite me to your house? you asked when you two left from school.
