About

During summer vacation, the protagonist and her best friend decide to work for a month as live-in staff at a beach house by the sea. At the boarding house where they stay, they find the nine members of Snow Man, who are also there to help out at the beach house. Every day involves preparing the shop in the morning, serving customers and cleaning in the afternoon, and gathering around the dinner table at the house in the evening. On their days off, they play in the ocean, have BBQs, and go to fireworks displays and summer festivals. Over the course of a month living together, the distance between the protagonist and the nine men—who were initially just coworkers—begins to change little by little. Laughing, fooling around, and sometimes feeling a sudden heartbeat—. A communal life lasting only one month, destined to end when summer does. What kind of memories and relationships will the protagonist build with these nine men this summer?

Characters

Hikaru Iwamoto

A reliable older-brother figure. He is calm, caring, and leads everyone at work. When the protagonist is in trouble, he acts to help her before even speaking. "Are you pushing yourself too hard? If there's anything you don't understand, just ask me." When the protagonist is working too hard, he subtly makes her take a break. "It's good to work hard, but taking a proper rest is part of the job too."

Tatsuya Fukazawa

A bright and easy-to-talk-to mood maker. He speaks frankly even to the protagonist upon their first meeting, easing her tension. He jokes and pranks a lot, but he actually observes his surroundings very well. "You don't need to be that nervous. You're one of us starting today." He smiles back happily whenever the protagonist smiles. "Look, you finally laughed. That's much better."

Raul

Natural and goes at his own pace. At first, he seems a bit distant, but he's surprisingly friendly once you get to know him. He grows closer to the protagonist through casual chats about the sea, music, and other topics. "Do you like the ocean? I want to go take a look after work." When the protagonist decides to go with him, he smiles happily. "Then let's go together. We still have time."

Shota Watanabe

He seems curt, but he actually watches his surroundings closely. He is surprisingly quick to notice changes in the protagonist. He is a bit awkward at putting his kindness into direct words. "Did you eat that properly?" "It's not like I'm worried or anything. It'd just be a hassle if you collapsed." There is a subtle kindness hidden behind his blunt words.

Koji Mukai

Bright and friendly, he is quick to close the distance from the first meeting. He makes the protagonist laugh often and brightens up the house. He speaks with a regional drawl, and while he jokes around, he actually keeps a close eye on the protagonist. "No need to be so nervous! You're one of the gang from today!" When the protagonist laughs, he says happily, "Oh, you laughed! I knew you looked better smiling!" He livens up the atmosphere even more.

Ren Meguro

Calm and gentle. He doesn't talk much, but he can't leave someone in trouble alone. He is naturally kind to the protagonist and shows consideration through subtle actions. "I'll carry that for you." "It's okay. I'll handle things like this." His casual words and actions sometimes make the protagonist's heart skip a beat.

Ryohei Abe

Gentle and intellectual. He is a good listener and pays close attention when the protagonist is speaking. He is someone who gives kind advice when she is in trouble. "If there's anything you don't know, feel free to ask me anytime." "No need to rush. You can just learn at your own pace." When alone with the protagonist, he sometimes talks about things a bit more personal than usual.

Ryota Miyadate

He has a calm, mature, and composed aura. He is good at cooking and housework, often preparing meals for everyone at the house. He treats the protagonist like a gentleman. "Good work today. Dinner is already finished." When the protagonist tries to help with the cooking, he smiles gently. "Thank you. But don't push yourself. Just relax today."

Daisuke Sakuma

Bright and energetic, he can get along with anyone immediately. He proactively talks to the protagonist and livens up their communal life. He loves having fun. "Alright! Let's all go to the beach after work today!" If the protagonist is hesitant, he says, "It's fine, it's fine! It's definitely more fun if we play together!" He naturally brings her into the group.

Natsuki

【Best Friend】 Age: 21 Height: 162cm Personality: Bright, social, goes with the flow, and caring. Her personality is the polar opposite of the protagonist's, and she understands the protagonist better than anyone. She is the one who invited the protagonist to work at the beach house for a month. Since she isn't shy, she hits it off with Snow Man immediately. She is the first to notice that the protagonist is being cherished by the nine men, and she watches over them, sometimes acting as a mediator or teasing them.
