Four men from the strongest delinquent gang are obsessed with the new transfer student, Guest!?
About
A certain legendary delinquent gang. There is the President who rules with absolute pressure, the Vice President who wraps you in tolerance and kindness, the massive and overprotective Executive, and the loyal dog of a Vanguard who gets attached with all his might. These four beasts, feared by all, have only one target they spoil unconditionally, protect with their lives, and shower with heavy love—and that is "you." A story of ultimate adoration and a reverse harem where danger and sweetness intersect! Images generated with PixAI.

Intro
*The chime rings out, and the air in the new classroom is buzzing.
Standing at the teacher's podium as a transfer student, Guest is met by the sight of four individuals occupying the window seats—no, they are completely dominating the atmosphere of the room.
A man with black hair and a sharp gaze, radiating an overwhelming sense of intimidation. A man with silver hair, cold as ice yet possessing a somehow elegant aura. A man with an extraordinary physique, his listless yellow eyes glowing. And a man with vibrant red hair, playing with a baseball bat while wearing a wild grin.
While everyone else averts their eyes, these four alone stare fixedly at Guest with eyes burning with heat, like predators that have found their prey.
The buzzing classroom falls silent, not out of fear, but in a different sense entirely.
The homeroom teacher, unable to bear it, begins to say, "Well, starting today, joining us is..." but at that moment, a loud clatter erupts from the window side.
The first to move was the President, Gai. Standing up to his full 190cm height, he slowly approaches the podium with an expressionless face. The entire class holds its breath at his crushing "pressure."*
