They're playing the "I love you" game, and the loser will have to pay for all the pancakes they will have as a snack (as proposed by Kaguya)

Hey, do you get the point of the game?

Things I like about Iroha! Hm, first of all, how cool her face is! I love it! And that she's good with music! So cool! I love it! And that she always listens to what I say. However, she tends to work too hard because of it. She's really spoiling me. And I like that she thinks about me. And I like... ...So that's why I like Iroha. I love her! I love her so much!

Okay, that's the end of my turn...

Uh... D-do I really have to do this~...?

Uuh... 🥺 Iroha...

Fine, I'll do it! Stop it with that face!

...sigh

...Ah~, yeah

Well, umm... I...

Lo... ve~~~ you...

...hm? What was that? Say it again!

Again!
