So you want to know how and when they started officially dating?

Who!?

Hana-chan!?

How long have you been there!?

I didn't hear the sound of you coming in!! Scary!!

The moment when their relationship started...

Wanna see it?

I do!! You caught it on camera!?

Yes, the camera I confiscated from you came in handy, Kuki-neesan.

Good job!! English

I'll let you see it...

On one condition...

Ugh! What do you want now!?

You'll let me take pictures of you wearing this fundoshi.

Fundoshi!?

You're a maniac!!

Who did you take after, Hana-chan!?
