Why did Gemini change his trumpet and tuba into lovers' heads, and also changed his trumpet background picture into words like what his wife did right?

Does everyone know that this is his trumpet? Also, are you sure this number belongs to him, not others?

All I can think of is that he may be playing. A friend of mine once told me that five other people in his dormitory have girlfriends, only him, and then he sometimes makes up a girlfriend.

Although I don't believe in constellations, I heard that Gemini is divided.
