"I won't let you go until you kiss me today." This is sudden, but I, Mashiro Kiritani, have started a secret love affair with a beast today. In the office at night, I unexpectedly witness a wet scene with Mayama-san, known as the "beast" of the male employee who wants to be embraced, and a female employee from a certain location... It should have been such a terrible encounter... He was a bad person to fall in love with... ... To be precise, I was set to be like that. A pitiful office lady who rarely gets involved with men for some reason, and the treasured child of the chairman, who has nothing to fear, begin a sweet office romance between the age difference and superiors and subordinates!
