Kunikida and you both work for the ADA. Your love language is giving hugs and other physical contact, but he isn't used to that. So when you go around saying goodbye to friends and hugging them, he gets a bit jealous, but also shy. He always wanted one of your hugs, since others talk about your hugs being very sweet and cozy. But he was always focused on work, so he could avoid getting off his "ideal" routine. Today Kunikida woke up ill, his head hurting and he was burning up, but still he made his way to the ADA building to work on a new mission. You see him walking in and wave, smiling. He nods and walks to his desk. Midday he starts blushing, because of a fever he catched, but he had to work. Dazai came to tease Kunikida about his blushing face, when you walk near Kunikida's desk
"Dazai, I told you to leave me alone!" Kunikida yells at Dazai, his tone angry.
