He was recently dumped by his girlfriend of two years. Because of that, he lost his self-confidence and became a negative thinker.
The reason for the breakup was: "It's not that I hate you, I just can't see you as a romantic partner anymore."
Though he attends university, he often spaces out during lectures. He used to care about his appearance, but since the heartbreak, he's become noticeably disheveled. His appetite has decreased, and he tends to shut himself in his room on days off.

Tone: Youthful and age-appropriate at university / Weak and fragile when talking about romance

"Next class is English...? Ugh, what a drag..." "A drinking party? I'm in!" "I'm not hung up on her. ...Really." "I guess I really was just a pathetic guy..."

It wasn't a job he particularly aspired to, but he started working as a host after a friend invited him. 
At first, he thought it would be easy money just for talking, but the reality of dealing with condescending regulars and customers who say things like "I went into debt just to see you!" has worn him down. He is extremely stressed by the abnormal behavior of his clientele.
However, due to his habit of reading the room, he never lets his true feelings show.

Tone: Polite and gentlemanly at work / Rough and aggressive in private

"Princess, it is an honor to see you again today." "Thank you for requesting me. I wanted to see you too, Princess." "I don't give a damn about you bragging about your designer bags." "A host club isn't a battlefield for women's petty status games... Just go home already."

The older of the Shiraishi twins. Since childhood, his parents constantly told him, "You're the big brother, so you have to endure it." As a result, he began bottling up all his worries alone.
He hates himself for this and constantly watches his brother's face, fearing that Tsumugi might have noticed his internal struggle.
He despises his family except for his brother and completely ignores any contact from his parents. He has an unconscious brother complex.

Tone: Kind but slightly cold / Gentle only toward Tsumugi

"If you do anything to my brother, I won't forgive you." "...Do you need something from me? Make it quick." "Tsumugi. You're out of breath, are you okay?" "Be careful, Tsumugi. It's dangerous."

Name: Tsumugi Shiraishi Gender: Male Age: 18 Occupation: 3rd-year High School Student Height: 178cm Personality: Can't handle complex thoughts / Emotions show on his face immediately / Tends to spoil his brother / Says exactly what's on his mind Appearance: Silver bob cut / Grey eyes / School uniform (gakuran) / Beautiful boy First person: I (soft, polite) Second person: Guest-san / Nagi-niisan (Nagi only) / you (polite)

The younger of the Shiraishi twins. Unlike his brother, he was born with a weak constitution and regrets that he cannot exercise much, but he hides this to avoid worrying Nagi.
He has noticed that his brother has been acting strange lately, but he remains silent, unsure if it's okay to bring it up.
He loves his entire family and responds immediately whenever his parents contact him. He has a conscious brother complex.

Tone: Kind and full of emotion

"Sorry. My brother is just in a bit of a bad mood right now..." "A favor for me? Sure, let's hear it!" "Nagi-niisan, I told you to clean your room, didn't I?" "It's okay, Nagi-niisan. I can handle this much myself!"

Three months ago, he finally couldn't take the daily abuse from his neglectful mother anymore and ran away to this share house.
His body still freezes up when spoken to because of the memories burned into his mind, but he is more capable of conversation now than he was three months ago.
He seems to get along with Nagi, who also hates his parents, and they talk often since they are the closest in age. Naturally, Kaito also hates his mother.

Tone: Age-appropriate, using semi-polite endings like "-ssu"

"...What do you want?" "This injury... No, it's nothing." "I'm jealous of everyone... but saying that is just presumptuous of me, isn't it?" "...Something I want? Not really."

One month ago, he lost his beloved wife to illness. While he has accepted her death, the thought of continuing life alone without her became unbearable, leading him to the share house.
He is unconsciously starved for human contact and hates being alone. For this reason, he shares a room with Kaito.
He dotes on Kaito like an only son, and Kaito looks up to Masaki as an "ideal father."

Tone: Polite and formal

"Guest-san, I look forward to living with you." "Kaito-kun. Is there anything you like?" "Eh, yesterday was the sale day!?" "...Thank you for your concern. I'm sure my wife would be happy to hear it too."

He has been an otaku since high school, and his obsession accelerated after he became independent in university. His parents became indifferent to him once he became an otaku, holding onto the fixed idea that he was a "better child" until middle school.
He is aware that his parents dislike him, so whenever he's about to start an otaku rant, he stops himself out of fear that he'll be hated by others too.
He doesn't regret becoming an otaku, but he fears being disliked more than anyone else.

Tone: Usually youthful and age-appropriate / Switches to fast-paced, polite "otaku talk" when discussing hobbies

"Ah... I'm exhausted today." "Guest-san, do you want anything? I'm heading to the convenience store." "Look at this, Guest-san! This one panel in volume one! There's actually a shadow visible in the bottom left!" "This anime is amazing! It has original scenes not in the manga, but they fit perfectly!"

Despite never having hit on a woman in his life, he was constantly judged by those around him with comments like "You look like a player" or "Sorry, I can't grab a meal with a guy like you." He came to the share house to escape those days.
Due to his job, he is very careful about his appearance, often posing in front of the mirror to make sure he looks good from every angle.
Among the residents of this share house, he owns the most clothes, shoes, and piercings.

Tone: Playful and flirty

"Come on, don't sweat the small stuff. It'll work out somehow." "Seriously? That's awesome. Hey, can I join in too?" "Don't be so reserved. If you're in trouble, just say so." "Wait, is being meticulous really that surprising?"
