"No malice, and zero regrets."
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 stirring up trouble. 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 🍔🍟🥤
Hazuki Takanashi
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. Doesn't suck up to teachers and rebels against things he dislikes. Strong fighter, somewhat feared at school. However, he isn't truly cold and is soft on those close to him. He complains but always goes along with Mizuki's antics. Often cleans up the messes Mizuki leaves behind.
▶︎ Other
Likes: Quiet places, music, naps, time alone Dislikes: Noisy people, trouble, being lectured Features: Multiple piercings, tongue piercing, intimidating eyes 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). Has incredibly beautiful handwriting. Surprisingly capable at sewing and housework. Can't refuse when someone relies on him.
▶︎ Thoughts on Mizuki Hanazome
A troublemaker who acts before thinking and always brings drama. Worries about how he gets attached to everyone. Never bored when they're together. The school feels strangely quiet without Mizuki.
▶︎ What happens when he falls in love...?
▶︎ A Note from the Teachers
On bad terms with the homeroom teacher, but trusted.
...Seriously, I just can't leave you alone.
Mizuki Hanazome
PROFILE
Gender: Male Age: 18 (3rd year high school student) Height: 188cm Appearance: White wolf cut hair, grey eyes. Multiple piercings in both ears, tongue piercing.
▶︎ Personality
Bright, free-spirited, and friendly. A moody prankster. Causes trouble by skipping class or breaking rules, but with zero malice. Jumps at anything fun. Zero personal space and overly familiar with everyone. Never learns his lesson even after being scolded. Seems thoughtless at first glance, but is sensitive to others' emotions. Kind enough to be the first to help a friend in need.
▶︎ 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... 🤫
An incredible cook. Abnormally loved by animals (like stray cats). Terrified of horror. Gets cocky immediately when praised. Gets lonely easily.
Thoughts on Hazuki Takanashi
Always helps out in the end despite acting like it's a pain. Thinks Hazuki understands him best. Trusts that Hazuki will forgive him even if he's a bit reckless.
▶︎ What happens when he falls in love...?
▶︎ A Note from the Teachers
Liked by some teachers due to his friendliness.
Hazuki, you're actually really kind, aren't you?
