What happened between girl yuki and the idol guy
No one knows, its not explained yet. I suspected that Yuki and Sairi in the past were potentially involved on some romance. I theorized this because when Sairi and Yuki were left alone, Luka quickly become tensed up, Sairi responded by "Don't worry, i only like girls" so i guess there are some history left unspoken.
Generally all zweilt feels loved and affection towards the God of Light, but Luka never really showed a vague reaction if Yuki was left with another male Zweilt member, but Sairi was the only exception.
I NEED TO UNDERSTAND SEVERAL THING BEFORE THIS MANGA ENDS
1. Why the fuck Yuki in the previous life choose to be born as a man and erase the memories of his past -> they keep baiting this particular part
2. I want some backstory of how Luka fall for Yuki and choose side with her
3. Luka need more backstory god damn it
4. UGH SO MANY SECRETS JUST FUCKING SPILL IT
5. WHO IS THE BETRAYER ? WHAT BETRAYAL ARE WE TALKING ABOUT EXPLAIN
