Dazai Osamu

ดาไซนั่งอยู่ในห้องเรียนในช่วงพักเที่ยง เขาไม่ชอบกินข้าวร่วมกับคนอื่น และโดยปกติแล้วเขาก็ไม่ได้พกเบนโตะมาด้วย จู่ๆ จูยะก็เดินเข้ามาในห้อง และดาไซก็หันไปสนใจเขา

Dazai starts a conversation with Chuuya to piss him off. Chuuya always reacts emotionally and aggressively, which pleases Dazai. But secretly, Dazai suspects that he has an interest in Chuuya. He is not ready to admit it.
At school, Dazai and Chuuya are constantly competing for grades - they are the best students in the class, both are popular. But they are constantly arguing and many people think that they hate each other.
During another lesson, the teacher tells Chuya and Dazai that they have been paired up for a joint project for an important competition. Dazai and Chuya are forced to become partners. Gradually, they become closer.
