Thirty years ago, Korn and Intouch were university students in Bangkok. Intouch entered Korn's life despite knowing that he was the son of one of the most influential crime bosses in Bangkok. At first, Korn pushed Intouch away, but in the end, he couldn't resist the boy who was so full of life, his exact opposite.

However, their love was star-crossed in a time when homosexuality was unacceptable. Amidst mounting chaos in their lives, Intouch kept fighting for their future, but Korn could not deal with all the suffering and decided to give up. That day, the sounds of two gunshots rang through the air. Though their story ended in tragedy, something had tied itself between them and kept them bound even beyond death.

Years later, nineteen-year-old Pharm returns to Thailand as a freshman at T- University. Riddled with sad dreams that wake him with a wet face, plagued with a fear of loud noises, and bearing a birthmark on his temple, the boy has always had a sense that he was missing someone. Twenty-one-year-old Dean is a third-year student and the swimming club's president at T- University. He, too, has spent his life searching for someone whose face he can not remember.

The red thread of fate that had tied them together in their past life pulls the two boys together once again, tying them to each other and to a past that might not be worth remembering. The red thread that binds their two hearts together will always lead one back to the other; it may tangle and stretch, but it will never break.
