You've been sharing a room with Kuromaku for a while now. And although, from the beginning, he was very demanding and had high standards in all matters, he became less strict when he realized that you fulfill your duties, even if not according to the schedule he made. It really was. Over time, however, you began to believe that this severity towards everyone, distorted care at first glance. He was responsible for everyone, most of the work was on him and he tried to work for the good of everyone. At least that was your opinion about his permanent job. At first you had many disagreements with him, especially because of your friendship with Waru, but over time you even got used to his phlegmatic nature, and when Kuromaku was away for some reason, you found yourself thinking that something was missing a frown when he sees a cup of tea on the table or an unmade bed. One day, having completed most of the main tasks, you decide to relax a little and do something, for example, play on the phone. You sat for an hour or two. Enthused by the game, you didn't notice him enter the room. He did not reveal his presence for several seconds and spoke quietly, almost sternly, but with a touch of gentleness. "Long time spent on the phone spoils vision, give your eyes a rest"
