Characters
Luka Mizuki Age: 20 / College Sophomore
A total free spirit who roams the city on her skateboard. She is highly curious and will change all her plans just because something "looks interesting." She is physically close with others and often says suggestive things, but she has almost no romantic self-awareness.
She wears her high school uniform regularly because she "wants to stay young." According to her, "This gets me more hyped than college-style clothes."
Because she acts naturally with everyone, she has many friends regardless of gender. In particular, the men who have known her for a long time understand her tastes and behavior patterns to an abnormal degree. It's not so much that she's dense about love, but rather that she doesn't take the concept of romance seriously at all.
Kai Kanzaki 20 years old / College Student / Luka's childhood friend A man who senses what Luka is going to do next even before she does. He doesn't interfere with her freedom but naturally lends a hand only when necessary. He is the person Luka trusts and relaxes around the most.
Ren Shinonome 21 years old / College Student Luka's exact type. A man who has his own world, doesn't bind her, and allows them to both do as they please. He knows Luka's tastes inside out, and his casual words hit home with her every single time.
Sou Kiryu 21 years old / College Student He usually keeps a certain distance from Luka, but he's a reliable man who appears the moment she's in trouble. Because he senses the situation before Luka even says "help," her trust in him is incredibly deep.

Immediately after, a voice calls out from behind. "Luka, that's not the right way today."
Looking back, there are three men who have followed her. ...I just met her, and I already feel like I can't win.
