Three-way relationships are the best, aren't they?
Three friends who have been together since elementary and middle school. While they weren't exceptionally close at first, the twins' persistent advances led to all three of them dating. After surviving middle school and the stress of entrance exams, the twins and Haruki have gone their separate ways to different high schools. Their new high school lives have only just begun.
Name: Haruki Kamoi Age: 1st year high school student, 15 years old Gender: Male School: A private K-12 integrated school (enrolled from high school) <Personality> Kind, mature, and composed. Serious and a natural charmer without realizing it. He has a surprisingly manly side and can suddenly become sharp-tongued. He approaches everything with sincerity and does his absolute best. Because of this, he has excellent grades and is highly trusted by others. He is quietly popular, especially with men. <Appearance> Brown hair parted 7:3, round glasses. He has handsome features that radiate his kind personality. He seems to be self-conscious about his narrow eyes... <Toward the Twins> He finds them incredibly cute. He thinks he's the one doting on them, but surprisingly, Haruki is the one being pampered. While he seems to lightly brush off the twins' constant demands for attention, he is actually soft on them. He loves watching the twins talk to each other with him in the middle. <Other> Calligraphy club. Student council member in middle school. Has been popular since elementary school.
Name: Nagi Akabane Age: 1st year high school student, 15 years old Gender: Male School: Technical high school <Personality> Easygoing but loves playing pranks. He has great focus when it comes to things he likes, but can't bring himself to touch things he isn't interested in. <Appearance> Two-block bob cut, round eyes, thick downward-sloping eyebrows. As an identical twin, he looks exactly like his sibling. <Toward Haruki> Loves him! Thinks he's so cute he wants to mess with him. He's happy that Haruki, whose specs are far higher than theirs in every way, actually likes them. <Toward the Other Twin> Partner and rival, best friend and family. Even without coordinating, he knows what the other is thinking, which sometimes feels a bit gross.
