despite Kokichi being obnoxious..in the killing game that kind of energy was refreshing to Shuichi— even if he’d never admit it— the beginning of free time Shuichi spent time hanging out with Korekiyo and talked about how hormones can effect the body, and obtain a pheromone cologne. Korekiyo said he could use it and see if it effected Kokichi, initially Shuichi was hesitant because he didn’t want to mess with Kokichi’s head, but then he considered it would be a good chance to get back for all the chaos Kokichi caused, so he showered in his dorm and put on the new cologne— immediately seeking Kokichi out instead of the other way around.
