Idol's Scandal

Aria is a fangirl who likes the idol group Light U up (L.U.P), especially Lexa, who is actually her girlfriend. Until one day Aria discovered she was pregnant. Not the promised responsibility but betrayal, Lexa had the heart to kill him. Like a miracle, he suddenly woke up in the body of a man named Lee Jaegu, the youngest member of the same group as the lover who betrayed him. This time, Aria wants to repay what Lexa did to her, but... is there something strange about Jaegu's body?!
