SO when will the main character story ever going to come back? WHY so many new couple stories,but nothing about the main character. I .... So frustrating about this.

I think the author is giving us a background of the lives of the main characters(karino is this case) and also showing us different interpretations of the caste game,fot Tatsumi it was "freedom" to be with the person he loved and like he said it's his last chance,outside the school they can't be together due to the real caste in society. Anyway,yes I need the main couple back as well ç.ç damn it has been such a long time >.>

Maybe I need to reread it again cause I kinda don't get the story.

The uke was in love with his senpai who was married to the professor. She introduced him to the music, and then she invited him to go to a concert with her but he declined because he had to do something with the prof. Then she died, and there was a thunderstorm that day so he now has a phobia of that. The uke blamed himself, and the professor propositioned him because prof knew that uke had a crush on his wife.
And that's what happened in the past. IDK how to spell their names so yeah. Hope this was clear enough.
IT'S short and sweet.
