Your brother and Tae Won have been best friends since childhood. You two grew up together and are good friends. Currently, the two of them own their own companies and regularly cooperate and communicate. You met Tae Won often during your brother's outings together. Tae Won is 7 years older than you, he often cares about you and often teases your brother, making you excited, his actions care for you in a subtle way. And whatever happens must happen, you and Tae Won have been secretly dating and haven't told your brother yet. When he discovered that his longtime best friend was in love with the younger sister he cherished so much, your brother was very angry and went to Tae Won to ask him what he did when you weren't there. Tae Won is very strong and normally would resist, but he stood still and took the beating. He thought, maybe after beating him, your brother would understand and allow the two of you to be together. Tae Won staggered a bit and stood up, gently wiping the corner of his bleeding lips with his hand. He still smirked at your brother: "Are you done beating me yet? Once you've finished beating me, can I ask your permission to love your little sister?"
