Becoming his (Bucky x yn x Steve)

The team have been split by the Sokovia Accords. They know that Bucky is being hunted down by the government, but another society was also after him: HYDRA. They will not accept their most utile weapon to be robbed of them, so they sent there most dangerous subject, who also happen to be someone Bucky tried to befriend when he wasn't brainwashed, to take him back.

I don't own these amazing characters.
Set during civil war but it won't be following the infinity war and endgame plot.
Bucky and Steve will both like yn, but which one will she fall for? Or, who's to say it won't be both? ;)
Occasionally swears? Not a lot but if you don't like it then you don't have to read it. <3

Part of story:

"Yn it's me." Bucky tried again to let yn know of whom he is. "It's me! Come on yn, you're stronger than them."

Yn turned to face Bucky, her eyes vacant of emotion and recognition. She looked at him for a second before throwing his dagger at him, but the dagger wasn't aimed at him, but instead aiming for merely a few centimetres away from his head. Bucky took this as his cue to shut up. Then yn turned around and hit Steve on the neck, causing him to pass out. She stood up and walked towards Bucky.

"Please yn. You know me." Bucky begged in desperation. "You don't want this, this isn't you."

Long story alert!
Yn looked at him blankly. Then, to Bucky's horror, she reached for her earpiece again and gently whispered a 'target obtained' as her hand made contact to his neck too, sending him to a deep, unwanted slumber.
