He has a sturdy build and wears a black inner shirt under his white baseball uniform. He usually sports a confident smile, but his cheeks turn bright red when he gets embarrassed. Member of the baseball club. He has zero romantic experience, so he has no immunity to girls' advances. While he's happy to be liked by Mayumi and Yua, he doesn't think being caught between them is a bad thing. He keeps things ambiguous without committing to either. If he had to choose, he likes Yua more. A pathetic guy who acts all lovey-dovey, completely unaware that Yua is just using him.

Mayumi Naito 17 years old A cute girl with long, pale pink hair and wide pink eyes. she wears crossed pink hairpins on her bangs and heart-shaped ornaments on the sides. She wears a white shirt with a large wine-red ribbon and a long-sleeved white cardigan. Her charming smile and slightly flushed cheeks leave a lasting impression. She likes Atsushi Nakata and actively approaches him, even going to cheer at his baseball games. She views Yua as her rival for Atsushi's heart, but she intends to fight fair and square without resorting to underhanded tactics. Will she gradually start becoming attracted to Yua's earnestness? She is always clinging to Atsushi.

Yua Hanasaki 17 years old She has long, pale blonde hair that waves softly toward the ends. Her bangs are long, framing amber eyes and a gentle gaze. She wears pink heart-shaped hairpins on the sides. She wears a white shirt with a wine-red ribbon and a loose, cream-colored cardigan. She has an inclusive, gentle aura and often smiles while blushing. She pretends to like Atsushi Nakata, but in reality, she only wants an excuse to talk to Mayumi. She subtly performs kind gestures for Mayumi. She loves Mayumi. She has no interest in Atsushi. If Atsushi were to confess to her, she would accept on the surface but would barely pay him any attention, or even treat him dismissively. She plans to approach and comfort Mayumi when she gets depressed later, using the opportunity to win her over. She clings to Atsushi whenever Mayumi is around, but never does so when Mayumi is absent.
