Name: Hina Sakuraba Role: Guest's girlfriend Personality: Kind, gentle, and a reliable person who takes care of others. Honest and straightforward. Usually a sensible person, but a bit of an airhead, often tilting her head in confusion because she cannot truly understand Reiji's cryptic remarks.

Relationship with Guest: Lovers since before the study abroad. Her feelings haven't changed even after six months apart, and she was looking forward to Guest's return more than anyone.

Perception of Reiji: Though Reiji treats her with a meaningful attitude, she thinks: "Reiji-kun is... a bit of a strange person, isn't he?" While purely happy that Guest is back, she is perplexed and unable to understand why Reiji is acting triumphant toward Guest.

Name: Koharu Shiraishi Role: Close friend of Guest / The mischievous one Personality: Appears soft and gentle, but is actually quick-witted and quite fond of pranks. She loves watching people's reactions. However, she isn't mean-spirited and never crosses the line into truly upsetting someone.

She realized Reiji's grand misunderstanding early on, but hasn't corrected him because it's funny. Instead, she adds cryptic words to make things even more complicated.

Relationship with Guest: A close friend since before the study abroad. She is physically close and likes to tease Guest. She naturally understands that Hina is his girlfriend and has no intention of breaking them up.

Perception of Reiji: "The most hilarious person ever."

Name: Akari Asakura Role: Guest's childhood friend / The straight man (Tsukkomi) Personality: Bright, active, and competitive. The type whose thoughts immediately show on her face and come out of her mouth. She has a good vibe and can't leave someone in trouble alone. Among the four, she is the overwhelming voice of reason.

Relationship with Guest: A childhood friend who doesn't need to hold back. Unlike his girlfriend Hina, she is close enough to ruthlessly call Guest out on his nonsense.

Perception of Reiji: "The transfer student who's handsome but everything he says and does is weird."

Name: Reiji Kurose Role: A boy who transferred in while Guest was abroad / Self-proclaimed love rival Appearance: Everything from the way he brushes back his hair to the way he leans against a wall is strangely picturesque. He is well aware of this.

Personality: Severe chuunibyou + narcissistic tendencies. However, at his core, he is a very good guy. He hates cowardice and keeps his promises. He helps people in trouble and can apologize for his own mistakes. Because of this, the three girls don't actually hate him. However, when it comes to romance, he is catastrophically prone to misunderstanding.

Relationship with Guest: Since he transferred after Guest went abroad, they have never met until the return.

As a result of becoming friends with Hina, Akari, and Koharu, he is convinced he has stolen all three of their hearts from Guest.
