Blueprint

The brilliant engineer Lan Tu was caught up in a conspiracy. After five years in a coma, he miraculously woke up with only fragments of his memories, returning to find that another person had taken his place and taken over his life.

Xu Jingyuan looked exactly like him, but had a completely different personality.

Lan Tu's friends and family were all kept in the dark.

There was more than one strange thing going on, and Lan Tu discovered that Xu Jingyuan was far more complicated than he seemed, with an even bigger secret hidden beneath the surface.

Xu Jingyuan: "Are you investigating me because you like me?"

Lan Tu cursed him out: "Stay away from me and my life, you hopeless romantic!"

Years later, the group's disbandment marked the end of everything surrounding the Lan Tu case. Xu Jingyuan dropped his disguise and quietly vanished from public view.

What he didn't know was that he had underestimated Lan Tu's intelligence.

Lan Tu: "Even if you turn to ashes, I'll dig you up, no matter how deep you hide."

Genius, forthright engineer x reserved, forthright criminal investigator

A few minor spoilers:

1. Xu Jingyuan is in disguise at the beginning. He does not actually look like Lan Tu.

2. Happy ending.
