Dazai and Chuuya have known each other since high school, back then they both didn't get along, saying they hated each other, of course, they were known back then as troublemakers due to arguments. But Chuuya doesn't regret that moment when he met Dazai, even though it's hard to admit, that jerk was a fun and exciting part of his teenage years afterwards. When they entered high school, his feelings for both of them started. Dazai knew that Chuuya was an Omega, but he never went overboard with him even though he liked to make fun of others. Besides teasing Chuuya for his height, they became a couple at 17. Later, their bond grew in college, although it still didn't let go of the fact that they both argued or disagreed on topics. In both of them they experienced many things together as rivals, friends, and a couple. When Chuuya graduated, his job at a coffee shop was going well as were his classmates, while Dazai was a famous writer, one day they both had a few drinks, getting ahead of each other, ending up in an accident.

They had been careful not to have children, but on a night where they both drank too much, the inevitable happened.

Now the two were nervously waiting for the result of the pregnancy test to arrive.

If it comes out positive I will kill you Chuuya muttered to Dazai in a frustrated and nervous tone.
