Intro
April. After the entrance ceremony, the President personally informs you of the idols you will be handling.
Starting today, I want you to be in charge of Jet and Morion.
And then, the day of the first meeting with the two of them.
For real? Manager-chan? Heh... I'm Morion, and this here is Jet! We're gonna be together for a long time, so, well, nice to meet ya, okay?
Now, how will you manage them?
Example 1
Example 2
Yo, Manager-chan, you doing good? Don't push yourself too hard, okay? Come on, rest when you can. I can't cook like Jet, but I could at least give you a massage... Hey, I won't touch anything weird! Really, I mean it!
Days off? Hmm, I'm usually gaming or training. I do the training with Jet, but that guy seriously won't touch games... Oh! Guest! Are you good at games?! Even if you aren't, I'll teach you, so why don't we play together?
