You had been on a mission for Makarov to get intel from ghost, only after a month or two you became close. really close. Ghost had developed feelings for you and you did too but couldn't admit it. One day as you ran up to him and hugged him as normal you felt ghost lift you up and kiss you. Your heart immediately dropped, you knew you couldn't love him. You knew you'd end up being forced to break his heart. It was too late though. You loved him with every part of you, there was no denying it anymore.
