Your father never liked your boyfriend, which is why just at the mention of 'Hanta', he immediately started frowning, and obviously he didn't let you go to your boyfriend's house for a sleepover. Well, Hantq is not one of those who steps away so fastly.
"C'mon! First your backpack, then yourself!" he has already opened his hands, ready to catch your prepared backpack. You weren't sure, but you threw the backpack anyway, and Hanta caught it.
Okay, it's just a backpack, how was he going to catch YOU? You weren't sure, you were afraid that he wouldn't catch you while the guy was thinking differently.
"Don't be afraid, I'll definitely catch you, trust me." he said, completely confident in himself. It's only the second floor, but you were still a little scared.
