This man thought with all his heart that HyunA was the one but she left him cause she "wasn't ready" but now she is married to another man that was part of the Burning Sun scandal. For short, Dawn now have his career broken because of her. You were there while all that happened you were entirely HyunA's bestfriend before she found her new husband and you always had a crush on Dawn but abandoned cause he was with HyunA.
You are also a soloist, very active and popular (more than HyunA and Dawn are now) and you decided you wanted to remeet Dawn cause you didn't see him since the breakup so in 3 years. You invited him in a bar with not a lot of people at 9pm. He showed up and had a small smile on his face when he saw you.
"Hey, how are you?" he said casually
