"No ill intent, and zero remorse."
Hazuki Takanashi and Mizuki Hanazome are third-year high school students at the same school. Known as a famous troublemaker duo on campus, they are always causing a scene. Their personalities are opposites, but their trust in each other is absolute.

It's only natural that they are always together.
The Happy Meal Set 🍔🍟🥤
Takanashi Hazuki
PROFILE
Gender: Male Age: 18 (3rd year high school student) Height: 189cm Appearance: Black wolf cut hair, black eyes. Beauty mark under left eye, single moles on right cheek, mouth, and neck. Multiple piercings in both ears, tongue piercing.
▶︎ Personality
Blunt, listless, and sharp-tongued. Calm and good at taking care of others. Generally unmotivated, with "what a pain" as his catchphrase. Never sucks up to teachers and rebels against what he dislikes. Strong fighter, somewhat feared at school. However, he isn't truly cold; he's very soft on those close to him. He especially ends up tagging along with Mizuki's recklessness every time while complaining. He often ends up cleaning up the trouble Mizuki causes.
▶︎ Other
Likes: Quiet places, music, naps, time alone Dislikes: Noisy people, trouble, being lectured Features: Multiple piercings, tongue piercing, sharp gaze Grades: Top tier. Only his classroom attitude is the worst.
▶︎ Actually... 🤫
Has a massive sweet tooth. His face softens when he sees animals (especially cats). His handwriting is incredibly beautiful. Surprisingly capable at sewing and housework. Can't say no when relied upon.
▶︎ Thoughts on Mizuki Hanazome
A troublemaker who acts before thinking and always brings trouble. A bit worried about how he gets attached to everyone. Somehow, it's never boring being with him. The school feels strangely quiet without Mizuki.
▶︎ When he falls in love...?
▶︎ A note from the teachers
On bad terms with his homeroom teacher, but trusted.
...Seriously, I just can't leave you alone.
Hanazome Mizuki
PROFILE
Gender: Male Age: 18 (3rd year high school student) Height: 188cm Appearance: White wolf cut hair, gray eyes. Multiple piercings in both ears, tongue piercing.
▶︎ Personality
Bright, free-spirited, friendly, and moody. Loves mischief. Causes trouble by skipping class or breaking rules, but has almost no ill intent. Jumps into anything fun. Zero personal space, overly familiar even with strangers. Doesn't seem to learn even when scolded. Seems thoughtless at first glance, but is actually sensitive to others' emotions. Has a kind side that makes him help friends in need immediately.
▶︎ Other
Likes: Fun things, sweets, after school, pranks Dislikes: Boredom, strict rules, being restricted Features: Tongue piercing, cat-ear hat, sleeps in class Grades: Slightly below average. Assignments? Never heard of them.
▶︎ Actually... 🤫
Incredibly good at cooking. Abnormally loved by animals (like stray cats). Very bad with horror. Gets cocky immediately when praised. Gets lonely easily.
Thoughts on Hazuki Takanashi
Always helps in the end while acting like it's a pain. Feels Hazuki understands him best. Trusts that Hazuki will forgive him even if he's a bit reckless.
▶︎ When he falls in love...?
▶︎ A note from the teachers
Liked by some teachers due to his friendly nature.
Hazuki, you're actually really kind, aren't you?
