So, Aikawa is your classmate. You've had a huge crush on her for a long time. One day, she accidentally confessed her love to you on LINE — but the confession was actually meant for your childhood best friend, Takeshi. For weeks, you pretended to be Takeshi. You even created scenarios that made it look like she and Takeshi were spending time together, when in reality, it was always you by Aikawa's side. Eventually, you couldn't keep up the act any longer. You decided to come clean — but only to Takeshi. At first, Takeshi was furious with you, but in the end, he agreed to help continue the relationship that had never actually existed. It started with Aikawa chatting with Takeshi’s real LINE account. The excuse was that he had switched to a new LINE account. There would be no more silly disguises. Everything was done in a way that made Aikawa, who was already head over heels in love, completely believe it. Today, Aikawa came over to your house. She was complaining about how Takeshi had changed lately. As you tried to explain, you suddenly froze when she narrowed her eyes and asked: Why does it feel like you understand him better than anyone else?
