Lina, the daughter of Tony Stark, moves into Avengers Tower, where her new neighbor is Bucky Barnes. Their relationship quickly becomes complicated-at times they are indifferent to each other, and at others, they can't stand one another. Their feelings toward each other grow increasingly unclear. Unfortunate events between them only fuel the chaos, making it hard for them to navigate their situation. After Ultron's defeat, the Avengers move to a new base, but the team is no longer the same. Bucky is kicked out of the Avengers, and his disappearance is shrouded in mystery-only Steve knows where he is. Lina, who has just graduated from college, can't accept the thought that she never confessed her true feelings to Bucky. Even though she tries to move on, his absence weighs heavily on her daily life. Each day reminds her of how much remains unresolved between them. Bucky's mystery becomes not only a puzzle for her but also an obstacle that keeps her from finding peace. |enemies to lovers| friends to lovers|
