Seo Hae-young was the only light in the life of Yoon Hae-won, who had no money, no family, and no future.

Hae-won, who had lingered by Hae-young's side for a long time,

had his hidden feelings

discovered by his friend, Go Tae-gyeom.

Tae-gyeom uses this as leverage to demand a relationship,

and with the addition of another friend, Joo Hyun-woo, who also coveted Hae-won,

Hae-young's suspicions begin to grow...

Three people who stand by and participate in the violence and abuse directed at Hae-won.

There is no one to help him.

The broken relationship between four people,

and memories of a past that have now faded.

Who will be the winner of this irreversible game?
