A video for an AU I came up on a whim

The premise is that basically, post-canon*, Senku is still working on a time machine. His 'relationship' with Luna is going downhill severly, as Luna is mad that Senku doesn't pay attention to her despite refusing to break up (he thought they already did). In the end they have a big fight in the laboratory, and in a fit of rage Luna activates the unfinished time machine. The machine turns out to be functional, but extremely unstable. Senku saves Luna by pushing her out of the way of the beam, but becomes trapped himself.

Following the activation, Senku finds himself in drastically different circumstances. The world was never petrified. His old man Byakuya is alive and well, and even married. Senku himself, turns out, is also married. To Luna, of all people. And they're expecting a daughter. In an attempt to save his Luna, Senku not just jumped in time — he hopped into a whole different timeline. With the same, yet so drastically people.

The story is about Senku adapting to this new environment, learning to love and respect his partner. Wheras there he spend months, in his world was merely a week. When Senku returns to his world, he finds out how worried Luna was about him this entire time. After this 'adventure', Senku learned to appreciate Luna a little bit more.

*The events of 4D science besides Chrome and Ruri's wedding are ignored.

I knew you in another life. You had the same look in your eyes.

Parentswitch AU?

(aka the AU where Luna is ByakuLee daughter and Senku is XenoStan son.)

In which Luna Wright is an adopted daughter of Byakuya and Connie Ishigami, and Senku is the son of Xeno Houston and Stanley Wingfield.

They both have two siblings (Chrome and Rei for Luna/Ruri and Kohaku for Senku) and often talk about them for hours. Luna is the big sister and Senku is the little brother of their respective families, so Luna knows how to deal with a type like Senku (obnoxious scientist baby brother)

Luna is studying medicine because she strives to become a doctor at the space station one day. She got her love for space because her mother is an astronaut.

Senku was homeschooled for most of his life, but enrolled into Hiromatsu University when he and Kohaku moved to Japan (Ruri stayed at home with their parents). There he met and quickly befriended Chrome through enemies to friends to besties speedrun, and later met Chrome's family, and therefore Luna.

Luna fell in love with Senku at first sight when she met him. Chrome and Rei knew that ASAP and now they tease the hell out of her for that. Byakuya sometimes joins the teasing, but it's more lighthearted. Luna also sometimes talks to the nightsky, hoping Connie, who is in space, can hear her.

Also Senku and Luna flying all the way to America to get the approval of Senku's family. Neither Senku and Kohaku consider it that much important but Luna insisted. Ruri and Xeno quickly took liking in her but she was absolutely terrified of Stanley and his judgemental gaze LMAO (still got his approval to date his darling son).

For a minute, Osomatsu looks satisfied, leaning back in his seat at this fancy restaurant. But soon enough that pride fades, as a realization dawned on him.
