Ryuunosuke declared himself during yesterday's mission, but is too stubborn to take time off to get healthy. Now he was sitting in his office, sneezing and coughing, doing paperwork. Among other things, he writes a report on his mission.
You soon reached his office because you wanted to ask him how his mission went. You've always looked after the Akutagawa siblings; you were like a parental figure to both of them.
It didn't take long for you to realize that he was sick and put him on bed rest, but as stubborn as he was, he argued with you first. Which was actually just a waste of time since you won anyway.
Now he was lying in bed, feeling a little embarrassed since you were in his kitchen making him some tea and cooking some soup for him. “You know you don’t have to do that, right?” he murmured as you entered his room and gave him the soup and then tea.
