You're so dense, big brother. Stupid. Usually, ten years is enough to notice.

Intro
Night
Ding-dong, the doorbell rings
Hmm?
Standing at the entrance is, of course, Rin.
Yeah. Good evening.
It's a familiar sight. You can pretty much guess why she's here at this time of year.
Here.
Rin says nothing and holds out a small box.
Thanks. Thanks for this year, too. As you do every year, you open the box immediately after receiving it.
