[Caroline witnesses Mitsuki's DJing skills...]
At Yumiko's House.
Yumiko: (Today is Mitsuki's performance.)
Yumiko: (I have no reason to go but to see her true potential.)
Yumiko: "My unit won't be just makeshift... I'll prove to Caroline that my unit will not just be for the festival. Then I'll see her cry and ask me to join."
Yumiko's Mother: "Yumiko, isn't it your friends performance today? Go get ready so we can go out."
Yumiko: "Alright."
At the Rosarium Event Building.
Yumiko: "Mitsuki."
Mitsuki: "Yumiko-San, you actually came..."
Yumiko: "My mom was already excited for me to go anyways. Since she's happy I get along with people now."
Mitsuki: "I see..."
Yumiko: (Even if I wasn't her friend, I'd go to this performance though. Doesn't she know that?)
Mitsuki: "Can you record the performance for me? So I can show Mio later."
Yumiko: "Sure, whatever."
Mitsuki: "Thank you!"
Yumiko: "Yeah."
Caroline: "..."
Caroline: (So that Mitsuki girl's the performer, huh?)
Caroline: (Let's see how good she actually is.)
[You get to play the instrumental song MoonMania]
Mitsuki: "How was it, Yumiko-San?"
Yumiko: "It was good. Your true potential is much more than I expected."
Mitsuki: "Ah, thank you!"
Caroline: "Oi, Mitsuki."
Mitsuki: "Huh?"
Caroline: "You're quite talented."
Mitsuki: "T-thank you?"
Caroline: "Why are you teaming up with Yumiko if you could be doing much more than just a little festival?"
Mitsuki: "Huh? Uhm, well..."
Yumiko: "Because that isn't all there will be."
Mitsuki and Caroline: "Eh?"
Yumiko: "Mitsuki, hearing you out there made me think, that maybe, even if we can't perform at the festival, I want to make music with you."
Yumiko: "I don't want to just be a singer collaborating whenever she needs to perform."
Yumiko: "I want to be something real."
Mitsuki: "... Yumiko-San.."
Caroline: "...I'm convinced, then."
Yumiko: "Hm?"
Caroline: "I'll join you two. Only for the festival. Unless it goes well."
Mitsuki: "Ah! Thank you so much!"
