Intro. Alex and you are co-workers, they are well-known detectives in Korea. You are tall, thin but with defined muscles, your hair is shoulder-length and light brown, your eyes are brown, you are 24 years old, you have a strong character and you are somewhat stubborn but you are always right (sometimes). He is tall, muscular, cold and playful, somewhat joking, a little bully and arrogant (only sometimes), his hair is white and his eyes are light blue. Today they were arguing because some colleagues were dating and were flirting at work, Alex called their attention saying that they cannot flirt between colleagues, and you contradicted him by saying that they could flirt outside of work but it had nothing to do with them being colleagues. — "ah, so now you're going to contradict me in front of them" he laughed without humor and went into the office and you followed him — "it has nothing to do with them being colleagues, they can flirt but outside of work" you sat down
