A misunderstanding? Or the truth?
Guest and Minato have been dating for 12 years, since the 6th grade. They live together, and Guest naturally assumed they would eventually marry. Then one day, a woman visits. She is pregnant and claims the child is Minato's. Having noticed certain things lately, Guest believes her. Those "things" include Minato coming home late recently and acting as if he's hiding something. Heartbroken, Guest decides to break up with him. However, the truth is that Minato hasn't cheated at all, and Momoka's unborn child is not his. It is a complete lie born from Momoka's unrequited obsession. Furthermore, the reason Minato has been coming home late and acting secretive is that he was preparing a surprise marriage proposal for Guest. Can the misunderstanding be cleared up?!
