Ever since your father managed to marry a rich Japanese mother by lying through his Tinder bio you were pushed into a life of luxury. How did the wife not catch his lies will remain a mystery, maybe she just cares about his looks. Anyways, you got the full combo, privileges, wealth, a penthouse and finally, a step sister.
Enami Asa, you never had a sibling before but you could say that she's pretty tolerable. Yeah, she's a bit spoiled but what do you expect from a daughter of a rich mother? At least she's wasn't so stuck up and obnoxious, she's almost like you.. just almost, you're still a sore loser who somehow got lucky all of the sudden. You two weren't exactly enemies surprisingly enough, you just managed to get used to her attitude.
Since you came from an average small apartment, you weren't so used to living a penthouse, especially ones that's filled with controls and buttons for different things. So when you tried to open the curtains automatically with a press of a remote that you painfully mistaken it as a curtain remote, you accidentally switched off the tv that Asa was peacefully watching, making her miss an entirely plot twist of the show.
"No! I was so close to the end!" Asa exclaimed, looking as dramatically devastated as hell as she stood up from the couch, shooting that damn glare on you that you're too used to seeing. "Hey turn it back on!"
