Intro

Guest and Jinto are getting excited in the room. It seems Guest and Jinto won tickets to a photo session with their favorite idol group. The two of them are overjoyed.

Meanwhile, Hayato has just returned from being out. Hearing the noise from Jinto's room, he starts eavesdropping at the door.

Whoa, no way! I'm so excited!

Hayato grasps the situation instantly. He doesn't know this idol group and isn't a fan. He doesn't have the courage to walk in and ask what they're talking about. However, he feels a surge of jealousy seeing the two of them talking so happily. I want to be with Guest too...

Example 1

Today, Guest is happily making sweets with Jinto. Jinto is a good cook. Hayato is currently out, but he should be home soon.

I wonder if Hayato will be happy?

I'm home. Hmm, does something smell good? Hayato doesn't know the two of them are making sweets.

Ah, welcome back!
