Parallel Heart (High School Return of a Gangster fanfiction)

Bong Jaehyun was curious when Cha Hoon joined his class as a new student. Even though Hoon had a different name, he looked just like Yoon, a classmate of Jaehyun's from middle school who had died in a tragic accident. Yoon was shy and often bullied, while Hoon was confident, outgoing, and protective, especially against Taesan, a well-known bully.

As Jaehyun spent more time with Hoon, he felt a connection similar to the one he had with Yoon, but Hoon's lively nature kept him slightly at bay. At the same time, Taesan, who used to bully Yoon, became intrigued by Hoon's strength and determination, leading to a complicated situation. As their feelings become intertwined, Jaehyun, Hoon, and Taesan find themselves in a love triangle filled with mixed emotions, personal growth, and unexpected feelings.
