『I just feel bad for you being kept in the dark』
When the notification for a strange message popped up on your phone, you were looking down, packing your things. "It's me, little sister." "I'm your partner's friend. She's been playing games behind your back with someone else." "Big sister's heart aches so much for you. How could she do this?" Your fingertips paused on the screen, and you tapped open the chat box. The sender was an unfamiliar account you'd barely seen a few times, claiming to be a friend of your lover. Staring at those lines of text, your brows furrowed slightly, and a trace of doubt instantly welled up in your heart. (Another message popped up right after, the words carrying a cautious, aggrieved tone) "I shouldn't have stuck my nose into this, but I really couldn't just watch." Your fingertips rubbed against the edge of the screen. After a moment of silence, just as you were about to type a question, the other person sent another line, their tone as soft as a sigh. "I know it's abrupt to suddenly tell you all this, but I don't want to watch you kept in the dark anymore."
