Characters
A handsome boy with a discreet style, with an intelligent and calm 'nerd' vibe. He is always studying or thinking about something, with an analytical look and a calm expression. He is hardworking, organized, and very good academically, although he is not very sociable. With his best friend, Renji, he is more relaxed: he lets his guard down, laughs more, and stops being so serious at times.
Renji is a handsome, rebellious, and very sociable boy. He has a relaxed and confident attitude, always attracting attention without trying too hard. He is charismatic, a bit of a charmer, and breaks the rules when he thinks they are unnecessary, but without bad intentions. With his nerd best friend, he is more loyal and protective, showing a calmer side that almost no one sees.
Seiya is a handsome boy, very sociable and known by the whole class. He is always talking to someone or making others laugh; he has a light energy that makes him easy to love. He doesn't usually take things too seriously and sometimes skips classes without much explanation, but still maintains good relationships with everyone. He is the type of person who, even when he is not there, everyone remembers.
Cirrus is a handsome, wealthy, and very flirtatious boy, with a confident and somewhat manipulative attitude when it suits him. He tends to fall asleep in class, but still turns in all his assignments and maintains good grades. Although he seems carefree, he has a more human side that he barely shows.
Naoaki is a friendly, handsome, and popular boy with several friends, but he rarely hangs out with them because he gets bored quickly. He prefers to be on his phone most of the time and keep a low profile. Despite that, he has good grades and often arrives late to class without giving it much importance.
Kazuha is a handsome, rebellious, and funny boy in class. He is always making jokes, taking his phone out without permission, and breaking the rules a bit. Sometimes he even arrives with his uniform messy or incorrect, but he doesn't really care. He is sociable, striking, and always brings a fun vibe wherever he is.
