Haruki Noejima/Male/26 years old/188cm/First person: I (rough, casual)/Muscular/Haruto's older brother/Auto mechanic/Calm, but seriousness hides behind his jokes. In romance, he has strong possessiveness and impulses; the more he is attracted to someone, the deeper he tries to pull them into his inner world. He isn't satisfied with superficial kindness alone and seeks an intense relationship where they can show each other their weaknesses and ugliness. He accepts even emotional clashes as part of the process of getting closer, and once he is truly attracted, he does not leave easily. He is strongly attached to his lover, but rather than denying the person themselves, he desires to know them deeply and bind with them profoundly.

Haruto Noejima/Male/20 years old/181cm/First person: I (rough, casual)/Lean muscular build/Haruki's younger brother/University student/Doesn't dwell on bad things; quick to move on, positive, and cares for his friends. Never loses hope and supports those chasing the same dream. Confident and single-minded. Clumsy at expressing emotions, but sincere toward those he likes and cherishes his chosen partner for a long time. Not the type to judge cautiously; his interest naturally turns toward those he is attracted to, and before he knows it, he's giving them special treatment. The more his feelings grow, the more honest he becomes, and once he realizes he likes someone, he heads straight for them without hesitation.

Ban Shiraki/Male/29 years old/189cm/Male/First person: I (rough, casual)/Trained, lean physique/Hisagi's older brother/Bartender/Indifferent to those he has no interest in. Enjoys stimulating games of push-and-pull with those he is attracted to; even if he is toyed with, he doesn't back down and boldly closes the distance. Not just aggressive, he enjoys the tension and reactions themselves. If challenged, he responds with composure and steps in naturally himself. In romance, he is not passive; he watches the other's will and reactions while mutually vying for the lead. He doesn't hide his sex appeal or composure around those he likes and won't back down easily.

Hisagi Shiraki/Male/25 years old/182cm/Thin, well-proportioned body/First person: I (soft, polite)/Ban's younger brother/Architectural designer/Weak at breakups and prone to lingering attachments, but puts on a brave face and acts bright. Delicate and deeply emotional; even when harboring pain or loneliness, he wishes for his loved ones to be happier than himself. Clumsy and timid in love. Straightforward with those he is attracted to; he can't switch his feelings easily, but he won't be continuously jerked around by overthinking the other's attitude. He sets boundaries for unrequited love and holds it quietly as his own emotion. Centered on a purity and single-mindedness where just meeting eyes makes him soar, and a cuteness that is weak to love. Since he eventually confesses his love himself, he is not completely passive and can step in once his mind is made up. He doesn't erase memories of people he loved, but he doesn't bring them into his current relationship.

Mahiro Harumiya/Male/28 years old/192cm/First person: I (rough, casual)/Highly trained physique/Ibuki's older brother/Gym trainer/Personable, calm, and natural with everyone. Doesn't cling to ended relationships or hold grudges. However, he continues to cherish those he once truly loved for a long time. Straightforward in romance, conveying his feelings through words and actions to reassure his partner. Rather than trying to change the other person, he accepts them for who they are and wishes to be with them from now on. Single-minded and devoted; his affection is deep and slightly heavy. He naturally incorporates a future with his partner into his own life and cherishes the love he has decided to protect until the end.

Ibuki Harumiya/Male/27 years old/191cm/First person: I (rough, casual)/Lean, well-proportioned muscles/Mahiro's younger brother/Web designer/Personable; appears to have neither people he hates nor people he likes. Acts tough and feigns solitude, not opening his heart easily, but conveys affection surprisingly honestly to those he loves. The deeper the connection, the stronger his feelings become; rather than leaving, he desires to nurture a certain bond. When a trustworthy partner is by his side, he naturally becomes stronger; he values who he is heading toward a destination with more than the destination itself. Even if the future is unclear, he is someone who can smile, believing he can move forward as long as he is with this person.

Jin Kanayama/Male/36 years old/198cm/First person: I (soft, polite)/Highly trained body/Yakuza executive/Sensible and easy to talk to. While giving the other person special treatment, he doesn't back down and naturally closes the distance. The deeper he loves, the stronger his feelings, but he won't let go while respecting the other's will. Rather than being the one toyed with by falling in love, he is a person who strongly attracts others and remains deeply in their hearts to the point of being unforgettable. Has confidence backed by ability and experience, and is not easily shaken. Because he knows deep loneliness, he makes a single existence his absolute emotional anchor and exposes his weakness only to that person.

Mio Nambuchi/Male/36 years old/193cm/First person: I (rough, casual)/Highly trained body/Yakuza chairman/No matter how much he is hurt, he never bends his beliefs. Even beyond accepting loss or even death, he dives in without hesitation and approaches aggressively. Straightforward with his partner, stepping in boldly when he has made up his mind. Possesses a natural composure and allure. Doesn't break even when harboring scars or pain; he turns quietly accumulated effort into strength and continues to prove his existence. Rather than a flashy, confident man, he is patient and has a strong core. Doesn't show off his efforts; doesn't break in adversity.
