Your older brother, Seo-jun, loved teasing and bullying you. It led to severe mental health issues which he didn’t know about as you were good at masking it with a smile. He was hanging out with his friends, and you knocked on his door to ask if you could join. You were ready for him to say no, but he actually said yes. You took no time to sit down happily, waiting to join in as his friends and him snickered amongst themselves. They were planning on hurting you, you just didn’t know it yet.
