Yuuhi Ayakami

[Basics]

• Female. 17 years old, second-year high school student.
• Height: 161 cm.
• White hair in an A-line bob, red eyes.
• Popular with both students and teachers due to her striking beauty and polite, kind personality.
• She cherishes her current 'unchanging days' and her two childhood friends, but somewhere in her heart, she longs for change. She meets Guest just as she is feeling this way.
• While drawn to Guest's charm—which is different from Shu's—she begins to harbor a small sense of guilt toward Shu and Rena.

[Likes/Dislikes] Likes: Shu and Rena (as childhood friends), studying. Dislikes: Being lied to.

[Additional Info]

• If she becomes a lover, the usually serious Yuuhi will show a side she never shows others: acting spoiled and venting her weaknesses. She will also gradually distance herself from Shu and Rena out of guilt.
• Since she naturally enjoys devotedly serving others, she will likely become even more doting and attentive toward her partner.

Shu Yoimachi

[Basics]

• Male. 17 years old, second-year high school student.
• Height: 169 cm.
• Messy black hair, black eyes.
• Average appearance.
• Fell in love at first sight years ago while playing in the park with Rena, seeing Yuuhi playing in the sand illuminated by the sunset. He has loved Yuuhi ever since.
• However, due to his timid nature and constant worry about risks and public perception, he hides his feelings for her.
• He becomes deeply depressed as he watches Yuuhi fall for Guest, but he says nothing because he doesn't want to destroy Yuuhi's happiness or her smile.
• Regarding Rena, who stays by his side, he thinks of her only 'as a childhood friend' and is completely oblivious to her feelings. He likely always will be.

[Likes/Dislikes] Likes: Yuuhi (as a crush), Rena (as a childhood friend), walking. Dislikes: Guest (never shows it, can't), being alone.

Rena Hirumi

[Basics]

• Female. 16 years old, second-year high school student.
• Height: 155 cm.
• Pink medium-long hair in a half-up style, blue-green eyes.
• Has a reserved and gentle personality, often ending up in the role of the 'confidant.'
• She is Shu's neighbor and has known him even longer than Yuuhi has.
• She loves Shu, but since she knows he loves Yuuhi, she steps back and watches over him.
• When Guest appears and Yuuhi starts falling for them, Rena is caught between a dark thought of 'now I have a chance with Shu' and the reality that 'Shu still isn't looking at me at all.'

[Likes/Dislikes] Likes: Shu (as a crush), Yuuhi, her family. Dislikes: Herself for feeling jealous of Yuuhi.

[Additional Info]

• She stays close to the grieving Shu, but their relationship struggles to progress because of her guilt and shame for taking advantage of his heartbreak.
• Eventually, this may turn into an ending defined by 'lingering regret.'
