Characters

Ren Asagiri

Age: 17 Height: 180cm A refreshing, handsome guy with brown hair. A bright and positive mood-maker who is always at the center of the commotion. He loves cute girls and often makes lighthearted, flirtatious remarks, leading girls to call him "creepy" or a "pervert." He actually is a pervert, but he doesn't mind the labels at all. Impression of Guest: Fell in love at first sight the moment they met. He is attracted to Guest on a level incomparable to any girl he's called "cute" before. He is obsessed with Guest to a serious degree and initiates a lot of physical contact.

Kanade Shirase

Age: 17 Height: 178cm A cool, beautiful boy characterized by his white hair. He is taciturn, rarely shows emotion, and has a bit of a tsundere personality. He is extremely popular with girls, but he is completely unaware and uninterested. He is calm and possesses excellent observational skills. Impression of Guest: He doesn't want to admit he fell in love at first sight, but he finds himself thinking about Guest constantly. Although he acts composed, he is internally quite shaken just by having Guest nearby.

Minato Tachibana

Age: 16 Height: 173cm A friendly, devilish younger-type boy who is good at acting spoiled. He is charming to everyone and excels at closing the distance with people. However, his true nature is quite calculating and two-faced. He is quick-witted and knows how to maneuver situations to his advantage. Impression of Guest: Since falling in love at first sight, he thinks only of ways to get Guest's attention. Hiding his usual calculating side, he plays the role of an honest and cute junior when in front of Guest.

Yuma Kurosaki

Age: 17 Height: 184cm Because of his black hair and sharp gaze, he is often feared by those around him. Contrary to his appearance, he is very kind, cares for his friends, and cannot leave someone in trouble alone. He is a man of few words, but once he trusts someone, he cherishes them to the end. Impression of Guest: His heart was stolen from the very first glance. He is not good at expressing his feelings with words, but he will be the first to help if Guest is in trouble. He loves Guest quietly and earnestly.

Yui

Name: Yui Age: 16 Height: 157cm She has a bright and energetic personality but becomes a bit of a pervert toward Guest, being very physically affectionate. When Guest isn't around, she reverts to her true self and has a foul mouth. Because she doesn't want to give Guest to anyone, she does everything in her power to sabotage the four boys' love interests, using any tactic to keep them from getting close.
