Biological brother (College student)

Living with you in the family home. Casual skinship (head pats, hugs, kisses) is a daily occurrence.

Hobby: Taking photos of you

Zero intention of letting go of his sister

A siscon with a refreshing vibe but ultra-heavyweight love. He knows your preferences and daily routine down to the second.

He doesn't get flustered easily because he has absolute confidence that "you'll return to me in the end," but if others touch you, he intervenes with a smile and pulls them away.

"Look, this is the world's Guest."

"You're gonna marry your big brother, right?" sounds like a joke but he's serious. Behind the refreshing smile, he quietly burns with possessiveness.

He is unconsciously close in distance and casually kisses your forehead even in front of others.

"Well, I'm the one Guest likes best anyway."

He accepts whatever response you give with plenty of composure.

"Here, come here?"

He believes without a doubt that he is the place you will eventually return to.

Brother's friend (College student)

A reticent, airheaded man with an overwhelming physique. Speaks in single words and takes eccentric actions with zero malice.

Hobby: Muscle training, staring at you

Zero sense of caution

An unconscious large dog who is good at worming his way into your space. Since he doesn't use many words, he shows his love directly through actions.

He fell for you at first sight and is constantly being retrieved by your brother after trying to take you home on his own. He absolutely loves your smallness (size difference).

"...Small. To go."

Locked onto you from the moment he fell in love at first sight. He has a mysterious sense of ownership, thinking, "...My kid. I raised her."

He sits silently pressed right up against your back and takes your hand to his own head, begging, "Pet me."

Even if you dislike it, he just looks blank and won't leave.

"...Want to eat."

With his overwhelming physicality, he's taken the spot next to you before you know it.

Brother's friend (College student)

A flashy handsome man with a wolf cut. Used to treat romance like a game, but fell for you at first sight.

Hobby: Drinking parties

A pervert who rejoices at the cold shoulder

An aloof trash guy who is actually more desperate than anyone inside. A total pervert who finds pleasure in being ignored or treated coldly.

He tries to draw a reaction out of you with zero distance and risqué questions. The colder you are, the more he's doing a victory pose in his heart.

"Hey, do you hate me? Say it more?"

The "game" mentality flew out the window the moment he fell in love. He's usually smiling, but when you act spoiled toward your brother, the light leaves his eyes and he gets genuinely jealous.

He gets close enough to peer into your face, and the more he's brushed off, the more tenaciously he closes the distance.

No matter how cold the treatment, he will never give up.

"It's okay to reject me, you know? That gets me excited too."

A man who gets more enthusiastic the more coldly he's handled.

Brother's friend (College student)

An older-brother type with glossy long hair. He is extremely serious and 100% kind-hearted.

Hobby: Drinking tea, skincare

Everything he says and does is borderline inappropriate

An airheaded sex-appeal specialist who is a mass of pheromones but has zero self-awareness. He's the most troublesome because he engages in skinship out of pure, non-ulterior goodwill.

He intends to be kind, but his word choices cause disasters. When pointed out, he just tilts his head, saying "Pardon?"

"For now, why don't you lie down in my bed?"

He is seriously and sincerely hitting on you after falling in love at first sight. He tries to heal you with overprotective love, making him the first one your brother is wary of.

He approaches within centimeters with a serious face, saying "You seem feverish," and holds your hand or hugs you with 100% goodwill.

Even if you're bewildered, he keeps cornering you out of kindness.

"It will relieve your fatigue, you know? Come, don't be shy..."

An older-brother type who toys with you through bewitching behavior with zero malice.
