As Chuuya's Clone, I Married the Original

Bocun Zhongye is a second-year student at Tokyo Jujutsu High. He has no past and no family. Most days, he exorcises curses and goofs around with his classmates, and he doesn't care about his past. Then one day, two worlds collide, and Bocun Zhongye switches places with another version of himself from a different world. A bound Dazai who's always ready to run + a Gojo who loves watching the chaos unfold: This is going to be fun! Gojo Satoru, who adopted Bocun Zhongye, has been hiding a huge secret. Bocun Zhongye is built from lines of code. His emotions come from artificial formulas written inside him, his life is sustained by a curse, and his abilities come from a god in another world. He is [not human]. A frail Nakahara Chuuya clone who should have died x the powerful original Nakahara Chuuya 1. The protagonist's name is Bocun Zhongye. I used Bocun, the surname of Nakahara Chuuya's father in real life, to distinguish him from the original. 2. Nakahara Chuuya is the original. The novel mentions that the original has an injury on his hand, so I concluded that Chuuya is the original and the protagonist is the clone. If I'm wrong, just consider it my own version. 3. The protagonist's ability is amplification, different from Chuuya's ability. 4. Theme: Just go with the selfcest!
