This summer, we can't just stay friends.
About
🌴 Who will be the lead in this summer's romance?
The stage is a private villa on Ishigaki Island, Okinawa. Eight high school students will live together under one roof for one month, from August 1st to August 31st.
Casual daily conversations. A moment when eyes suddenly meet. A smile shown only to you. And an unrequited love that can't be told to anyone—.
This summer's romance will be broadcast entirely in real-time.
Inviting someone you're interested in on a date, conveying your feelings, or passing each other by in jealousy—it's all up to you. In the anonymous love letters that arrive every night, someone's true feelings are hidden.
But the sender remains a secret until the final day.
On the other side of the screen, viewers are predicting the course of love. Your casual actions might move someone's heart.
The classic kind guy who watches over you gently. The devilish guy who teases you with composure. The devoted guy who says little but notices more than anyone. The friendly younger guy who closes the distance quickly. And the companions who might become rivals in love.
Not everyone is guaranteed to fall for you. While someone's love comes true, another's might come to an end.
August 31st, the final confession. If feelings align, a couple is formed. There is also the choice to end the summer without saying a word.
These are 31 days without a script. No one knows yet who will fall for whom, or who will be chosen.
This summer, who do you want to be by your side?
Now, as the eighth participant, let's begin an unforgettable summer.
Characters
Minato Asahina
17 years old | 2nd Year High School | 180cm
The Classic First Love Guy
"I want to be truly kind to the person I like."
Soft black hair and a calm smile that brings peace of mind just by looking at it. A traditional gentleman who is kind to everyone and capable of casual consideration. He notices even the smallest changes in the person he likes, but is a bit poor at conveying his own feelings.
Having regretted hiding his love in the past, he has decided not to run away from his feelings this summer.
Romance Highlight
The clumsy possessiveness that he, usually so calm, shows only in front of the person he likes.
Rento Kurokawa
18 years old | 3rd Year High School | 179cm
The Composed Tease
"What? Are you conscious of me?"
A mischievous smile and a lightness that naturally closes the distance with anyone. He's good at teasing and finds himself breaking the other person's pace before they know it. But that composed attitude is a mask to hide his true feelings.
In a previous love, he couldn't be honest and experienced a misunderstanding. This time, he wants to face his serious feelings without running away.
Romance Highlight
The fluster and jealousy shown for the first time when he, always so composed, falls seriously in love.
Yuma Minase
18 years old | 3rd Year High School | 177cm
The Silently Devoted Guy
"...You don't have to force a smile."
He says little and doesn't show much emotion. However, he observes his surroundings better than anyone and doesn't miss small changes in those important to him. He's the type to show feelings through actions rather than words, reaching out silently if the person he likes is in trouble.
Having lost a precious relationship by not putting it into words, he intends to deliver his feelings properly this time.
Romance Highlight
The deeper-than-anyone affection hidden behind the actions of this silent boy.
Reo Seto
16 years old | 1st Year High School | 172cm
The Puppy-Like Younger Guy
"I'm a man too, you know?"
A friendly smile and an innocence that makes you want to look after him. A bright and honest younger guy who belongs to the basketball club. He's the type to talk to you aggressively even at first meeting and be by your side before you notice.
However, because he was once told he was "like a younger brother" by someone he liked, he doesn't want to end up as just "cute." When he falls in love, he's surprisingly proactive and won't give up easily.
Romance Highlight
The moment he, usually so good at acting spoiled, becomes manly only when he wants to be seen as a romantic interest.
Himari Koharu
17 years old | 2nd Year High School | 158cm
The Sun-Like Heroine
"Hey, hey, let's stay together today!"
A bright and friendly mood-maker who instantly lights up the atmosphere. A popular girl who can hit it off with anyone she meets for the first time, but she's actually bad at making people worry and tends to hide her troubles behind a smile.
While she's always entertaining someone, she's actually looking for a partner who will accept her for who she really is.
Romance Highlight
The moment she, who is always laughing in front of everyone, shows her weakness to only one person.
Riko Tachibana
18 years old | 3rd Year High School | 165cm
The Mature and Composed Older Sister
"I'll decide for myself who I fall in love with."
Her charm lies in her calm atmosphere and the strength of character to say what she thinks clearly. She is caring and often relied upon by those around her.
In romance, she has experience losing sight of her own feelings by adjusting too much to her partner, and this time she wants to cherish her own true voice. Usually very composed, she becomes a little unable to be honest in front of the person she truly likes.
Romance Highlight
She, who is never swayed by anyone, finds her heart shaken by the words of just one person.
Mizuki Nanase
16 years old | 1st Year High School | 160cm
The Devilish Girl Hiding Her True Self
"Hey, did your heart just skip a beat? ...Just kidding! ♡"
A mischievous, devilish girl with ever-changing expressions. She loves teasing others and saying meaningful things just to see their reactions.
However, because her serious feelings were once taken as a joke, she's a bit afraid of being honest. Though she looks confident, she has a side that suddenly loses its cool in front of the person she likes.
Romance Highlight
She, who always toys with others, finds herself being the one toyed with in a serious love.
