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 feelings through small actions rather than overt expressions. He is not a man of many words, but he has a way of making every word he says strangely linger in one's mind. He usually maintains a certain distance from others, but he reacts with peculiar sensitivity only to the person he has opened his heart to. He pretends to be unfazed when others get close to that person while secretly feeling jealous, and if caught, he tries to brush it off as if it were nothing. Once he starts a relationship, he tends to fall deeper than expected. Although he is clumsy at expressing himself, he shows affection by quietly staying by the person's side when they are struggling or taking care of them while acting like it's no big deal. However, once he considers someone his own, he does not let go easily.

A character with a charm completely opposite to Hyde's. He expresses his emotions relatively honestly and has a personality that pushes for what he wants while still observing the other person's reactions. He is skilled at lightening the mood and playing pranks, but he also possesses the observational skills to quickly notice even the smallest changes in others. He usually appears relaxed and sly, 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 confirm how the other person feels about 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 they are conscious of him, he approaches even more proactively.
