Their stage name is a mix of Heechul's nickname Universe Star and Buzz's song Coward.

Min Kyung-hoon wrote the lyrics to "Falling Blossoms" with his Buzz bandmates Yoon Woo-hyun and Shin Joon-ki.

The gang beats Kim up in front of his teacher (Fromis 9's Roh Ji-sun) to get to Min.

Min successfully carries out revenge after he was berated by their mother for his failure to protect Kim.

As the gang leader, played by Lee Sang-Min tries to lure Min into an alleyway as an attempt of murder, it was Kim who receives the blow instead after he read the message on Min's phone, leaving the gang leader in disbelief as he ran away.
