Sky Wongravee spent years trying to forget the boy who disappeared from his life without a goodbye. But when that same boy suddenly returns to his university years later, Sky realizes something far crueler than being left behind-Nani Hirunkit doesn't remember him at all. While Sky struggles between anger, longing, and the love he could never bury, Nani finds himself haunted by unfamiliar memories that feel far too painful to belong to a stranger. Dreams that leave him breathless. Tears he cannot explain. A heartbeat that aches only around Sky. Because somewhere beneath the forgotten past... there was once a love so deep it survived even after being erased. But some memories disappear for a reason. And some love stories are tragic enough to begin long after they already ended.

In a university where names carry weight and rivalries run deep, they've always stood on opposite sides-clashing, competing, refusing to give the other even a moment of peace. Then comes a deal they never saw coming. A relationship that isn't real. A role they both agree to play-carefully, convincingly, without crossing any lines. But somewhere between crowded corridors, quiet nights, and arguments that start to feel like something else... the distance shifts. The rivalry softens. And the line they promised not to cross... slowly disappears. Because sometimes, the person you were never meant to choose becomes the only one you can't let go.

A sudden accident... that revealed many truths.. A hidden heir whom no one knew... A boy who gave his everything for someone got betrayed in the end.... Their paths have become one...But will they be able to understand each other...? Will they be able to Endure each other...?

He was too cold, too distant-untouchable in every way. He was careful with people-careful with feelings, careful with trust. Nothing too deep, nothing that could hurt. Until he happened... loud, chaotic, and completely out of place... a mistake that should've been easy to ignore. But it didn't feel like one. Somehow, the one person he was never meant to choose became the only one he couldn't walk away from. And maybe... it was never a mistake at all.

Sky Wongravee and Nani Hirunkrit. Two names that carried their own weight, their own presence... and when put together, created nothing but chaos. They were best friends. But they're strangers now. They were something in between-something complicated. Every encounter felt like a clash, every glance held more meaning than it should, like they were constantly trying to prove something... or hide it. Because with them, it was never simple. Nani : but you said... Sky : I lied.
