Kuroko Tetsuya was very sad because there was always a group of gangsters at the door of his office who regarded it as a gathering place.
Kise Ryota was very sad. After changing his job, he had no reason to find Kuroko every day to cultivate feelings.
Aomine Daiki was very sad because there was always a fierce-looking guy who claimed to be his younger brother but was so courteous to his crush.
Murasakihara Atsushi was very sad. He was obviously the first person to meet the little black boy, but he was preempted by several other guys in everything.
Midorima Shintaro was very sad. He was a well-known doctor and ended up working in a little-known small office.
Akashi Seijuro was very sad. The little bamboo horse he had held in his hands since he was a child suddenly flew away. Not to mention that there were many eyesores around him.
Several sad guys got together and formed a firm to find more sad people to work with.
