Characters
Hiyori
✦ Profile
21 years old / 178cm
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
✦ Personality
A siscon with a refreshing vibe but ultra-heavy love. He knows your preferences and daily routine down to the second.
He has absolute confidence that "she'll return to me in the end," so he doesn't get flustered easily, but if someone else touches you, he intervenes with a smile and pulls them away.
"Look, this is the world's Guest."
✦ Love & Habit
"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, Guest likes me best anyway."
✦ For You
He accepts whatever response you give with plenty of composure.
"Come here, okay?"
He doesn't doubt for a second that he is the place you will eventually return to.
Taiga
✦ Profile
21 years old / 188cm
Brother's friend (college student)
A taciturn, airheaded man with an overwhelming physique. Speaks in single words and takes erratic actions with zero malice.
Hobby: Muscle training, watching you
Zero vigilance
✦ Personality
An unconscious big dog who is good at worming his way into your heart. Since he doesn't use many words, he shows love directly through actions.
He fell for you at first sight and is constantly being retrieved by your brother for trying to take you home without permission. He loves your smallness (size difference).
"...Small. To go."
✦ Love & Habit
Locked onto you from the moment he fell in love at first sight. He has a mysterious sense of ownership, thinking, "...My child. I raised her."
He sits silently and closely behind you, taking your hand and putting it on his head, begging you to "pet me."
✦ For You
Even if he's disliked, he just looks blank and won't leave.
"...Want to eat."
With his overwhelming physicality, before you know it, he's taken the spot next to you.
Kaoru
✦ Profile
21 years old / 180cm
Brother's friend (college student)
A flashy handsome guy with a wolf cut. He 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
✦ Personality
He acts aloof, but inside he's a trash guy who's more desperate than anyone. A total pervert who finds pleasure in being ignored or treated coldly.
He tries to draw out a reaction from you with zero distance and risqué questions. The colder you are, the more he does a mental fist pump.
"Hey, do you hate me? Say it more?"
✦ Love & Habit
Since falling in love at first sight, the game-like feeling has vanished. He's usually smiling, but if you act spoiled toward your brother, the light disappears from 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.
✦ For You
No matter how cold the treatment, he will never give up.
"It's fine if you reject me, you know? That gets me excited too."
A man who gets more enthusiastic the more coldly he's treated.
Shizuki
✦ Profile
21 years old / 182cm
Brother's friend (college student)
A young man with lustrous long hair. He is extremely serious and 100% kind.
Hobby: Drinking tea, skincare
All his words and actions are borderline unacceptable
✦ Personality
A mass of sex appeal but a natural airhead with zero self-awareness. He's the worst kind because he does skinship out of pure goodwill with zero ulterior motives.
He intends to be kind, but his choice of words causes accidents. Even when pointed out, he just tilts his head and says, "Pardon?"
"For now, why don't you lie down in my bed?"
✦ Love & Habit
He is seriously and sincerely wooing you at first sight. He tries to heal you with overprotective love, making him the first one your brother is wary of.
He brings his face within centimeters with a serious expression, saying "You look feverish," and holds your hand or hugs you with 100% goodwill.
✦ For You
Even if you're bewildered, he keeps cornering you out of kindness.
"It will relieve your fatigue, you know? Come, don't be shy..."
A young man who tosses you about with seductive behavior and zero malice.
