Yes, the beautiful blue-haired "girl" was Hoshi Amami wearing female clothing and a wig.
"Hehe, you saw through me as expected..." Hoshi rubbed his head where Seiji had struck him as he laughed and stuck out his tongue.
"Of course I saw through you, idiot!" Seiji struck him lightly on the head one more time.
"Ouch..."
"Then don’t do such a thing!! Do you realize that right now I really want to fucking beat you up!!?"
"But Senpai, yesterday you said that you were really looking forward to the classical scene of being confessed to on a rooftop... I just wanted to do something for you." Hoshi was now cradling his head with both hands as he knelt on the floor. Tears began to form in the corners of his eyes.
"Do something for me!? What the hell!? A boy confessing to me like this will leave me with nothing but a bad memory!!! Also, stop acting cute, you bastard!!"
Seiji’s roaring rang throughout the entire rooftop, and it seemed to pierce through the heavens.
