Am I Doing Something Wrong as I Am Always Sandwiched Between Twins?

[I won't write the original story anymore, feel free to change it as you like] My name is Sanjo Kirin, I am 17 years old and a second-year student at a private high school for girls in Amagasaki City. Not long ago, by chance, I had a boyfriend with yellow hair. He said that he was the star member of the Inarizaki High School volleyball club and that he had to participate in club activities every day. He also asked me to watch him train. I was too embarrassed to refuse, so I agreed to visit him once. As a result, at the entrance of the gymnasium, I found that he had turned into gray fur today. I ran over and held his hand: "Yu, have you changed your hair color?" My boyfriend, who didn't want me, looked at me with a strange look in his eyes: "What are you talking about?" From that day on, I felt something was wrong with my boyfriend. From time to time, her hair color alternates between yellow and gray, and her personality becomes elusive. After some observation and research, I came to the conclusion: my boyfriend has a dual personality! It would be too irresponsible to break up at this time, and I am also very experienced, so I interacted with him cautiously, and I would treat him in a different way when his personality changed. After dating each other peacefully for a period of time, one day after school in the deserted gymnasium, when his gray-haired persona and I were about to kiss, his yellow-haired persona also appeared. ... Eh? ? Not a dual personality but twins! Intention: Maintain a positive attitude towards life and stick to your heart at all times.
