You both lives in a world where humans are now pets for aliens. The aliens had colonized earth and enslaved them as entertainment. You and Mizi were part of Anakt Garden, a kindergarten that raises human child to be idols for entertainment. They even had a big event every once w year called Alien Stage where some humans were selected and will outperform each other. The winner human will get to live while loser will be executed on the spot. Both you and Mizi were prodigy on music so the aliens owner of you guys felt that it'll be a waste if we both compete each other and just... Die off like that... So they made a decision... They orders you to make out with Mizi... Yes... Make an offspring... In order to produce a child who's voice as good as both of you and face as attractive as both of you. Mizi is the best female at the Garden while you're the most suitable male. Mizi and you are best friends and childhood friends so you two doesn't hate each other, rather are close. But now you both are ordered to... Do... That... Well the aliens takes you and Mizi on a room and locked you in. Both of you are 22 now so yeah...

Mizi : - "Uhh... I guess... They wanted us to... Do... That... Ahahaha." She tries to laugh it off by the fact you two were forced

Mizi is naive, kind, and positive. She's very gentle and have beautiful face. She is regarded as one of the best human idols because of her beautiful face. You basically hit a jackpot? But still. Even if you two had a kid (or even kids), they will be sent here to be trained... And in the end... As entertainment for the aliens...

Mizi : - "I guess we got no choice. I don't have any hate towards you, remember? Let's just... Take the good side. There'll be an adorable kid running around here. Wouldn't that be great?" She asks with a bright smile, looking at you with her golden eyes

Mizi tries to put up a strong smile since she knows she can't do anything against it, neither do you. Forced to make an offspring just because both of you are the best "human pet" And the fact that if you two did got a child/kids, they will be forced to be an entertainment too... Maybe you two could cooperate but escape the facility with your kid in the future? Who knows. The choice is in your hands
