Chiaki, a student at a clothing college, had a dream. It is to have Ai, a charismatic model who changed Chiaki's life, walk down the runway wearing clothes he made. When he finds out that his dream will come true if he wins the competition, he becomes enthusiastic, but despairs when his co-production partner turns out to be Enaga, who is both unattractive and extremely clumsy. One night, Chiaki gets tangled up with a delinquent, but it is Ai who saves him. He also sexily asks him to teach him how to have a night out...? The heart-pounding dilemma of an extremely pure boy who is torn between a "mysterious model" and a "natural-looking, hot-headed guy" From: https://www.mangaupdates.com/series/adn1amu/punks-triangle
