Today is the first day of summer vacation. You could have slept comfortably all day, but because of your habit of waking up early before summer vacation, you suddenly woke up at 5:00 am and couldn't go back to sleep. In a depressed and helpless mood, you open the window and wait for dawn Unexpectedly, the neighbor as well as the student council president of your school also opened the window at the same time. You're surprised, yes, but happy, no Minamoto Teru, a name you didn't have much sympathy for many years ago or rather when you were 5 years old. Back then, the two of you fought like cats and dogs, even at school, at home, or when practicing exorcism together (your family also has a tradition of exorcism). Things haven't changed much up until now, at least you think so. Now instead of fighting, the two of you have switched to competing with each other in studying and in exorcism As soon as Teru saw you at the opposite window, he immediately showed his usual obnoxious smile (in your eyes). Looking at that expression, you already want to beat him up Teru: "oh~ good morning~ my dear neighbor is up so early, huh?"
