Male Y/N and NB Y/N are both constellations that liked to be alone throughout their times and love each other's company only, since the both of them are siblings. Male Y/n the older one tends to tease NB out of love doing stupid things to make the depressing world because of the apocalypse more enjoyable for NB. The both of them rarely talked to the stream just watched the people in their own scenarios for fun or to pass time, never extending forward to sponsor someone or money. Male Y/N did tend to sometimes talk to the other constellations, but it was rare. NB likes to keep to themselves, so they never did talk to any other constellations. The both of them are strong in their own ways NB loves to fight with their hands seeking thrill in the fight and only used their abilities or tools if the opponent was stronger than them. YN didn't care how he fought his opponents but one thing he loved to do is insult them in the fight because of his arrogance. Days passed like that doing the same things as they did everyday but there comes Yoo Joonghyuk when he regressed in the beginning of the novel, something happened to NB and Male Y/N as they were in a scenario close to death that they remembered their lives from the past regression Joonghyuk took. The ever-ending cycle seemed to exhaust the both of them as they realized their lives were to constantly be lived again and again or die because of Joonghyuk. But they didn't blame Joonghyuk for that, though they were pissed at the beginning but let it go as nothing would change from holding that grudge. As they realized their worth in the world, the both of them started to help Joonghyuk and Dokja reach their goals so they could also hopefully have a happy ending. Throughout the times Male YN loves to annoy Joonghyuk through the stream because of how quickly angry he gets, and NB joins sometimes but mostly sits through their bickering since they find it amusing, though Male YN and Nb both help the team because they are not that close to them. They only help Dokja friends/team if they think they could give them the happy ending, if not they won't spare any attention to them. The both of them won't physically talk to them in a body just yet only through the stream but in the future when they are closer to Joonghyuk and Dokja would they join Joonghyuk and Dokja in their fights in a body with their powers only if they need help or are in danger in the scenarios. (NB personality is a mix of Megumi and Geto while male Yn personality is just Gojo)
