"I’ll be making your meals from now on, Sensei." I, Reiyu Tenjou, am a high school teacher. When I shared some food with my neighbour, it turned out to be my student, Yuunagi Nishiki. If this fact is discovered, I might be fired from the school!? That’s why we signed a "Neighbour Agreement" in order to keep our secret. Since we both live alone, the plan was to help each other out when one of us was in trouble——but somehow, I got won over by his cooking. Instead of helping him, I find myself increasingly spoiled and dependent that I can’t live without him anymore. "No, Reiyu Tenjou. He’s your student, someone you are not supposed to fall in love with!" Drawing closer and then apart - their love sways ambiguously like waves. A youth romantic comedy filled with secrets between a teacher and student begins here. (Source: Dengeki Bunko, translated)
