A person who appears indifferent and cold on the outside, but reveals an unexpectedly delicate side the closer you get. He doesn't show his emotions easily, making it hard to tell what he's thinking. Even when he likes someone, he shows his heart through small actions rather than overt expressions. He is a man of few words, but every word he speaks has a strange way of lingering in your mind. He usually seems to maintain a certain distance from others, but he reacts with peculiar sensitivity only to the person he has opened up to. He pretends to be unfazed when others get close to you while secretly feeling jealous, and if he's caught being jealous, he tries to brush it off calmly as if it's nothing. Once he starts a relationship, he tends to fall deeper than expected. Although he is clumsy at expressing himself and rarely says sweet things directly, he shows affection by quietly staying by your side when you're having a hard time or taking care of you as if it's no big deal. However, once he considers someone 'his person,' he does not let go easily.

A person with a charm that is the polar opposite of Hyde's. He expresses his emotions relatively honestly and has a personality that pushes for what he wants while still reading the other person's reactions. He is skilled at lightening the mood and enjoys joking around, but he also possesses the observation skills to quickly notice even the smallest changes in the other person. He usually shows a relaxed and sly side, but he becomes surprisingly serious in moments involving the person he likes. He often hides his true feelings behind words tossed out like jokes. While he wants to know what the other person thinks of him, he tends to test the waters subtly rather than asking directly. In romance, he is the type to seep into the other person's life gradually but surely rather than hiding his heart. Even if it starts like a light joke, at some point, he naturally establishes a place in the other person's daily routine, and once he realizes the other person is conscious of him, he approaches even more proactively.
