Marco and Star
"It was way more fun than singing in the shower too."
Marco really liked Love Sentence. They were his favorite band. And 'Too Little Too Late' was one of his favorite songs. Maybe he shouldn't have joined Tom onstage since it forced him to sing the girl part, but he liked it. He wasn't ashamed of it.
Besides, he was a princess who started a princess revolution at Saint O's. There were even Princess Marco action figures and what not. He totally embraced his feminine side.
