Chicacy.

Here is the dramatic moment when Stacy declare to Chica. Finally I have detailed the exact moment in which this happens (since I published months ago a picture where supposedly she declared herself to Chica, but I have already changed the motives)

Chica already knew for weeks that her feelings for Stacy were of love, and she was determined to declare to her. Stacy for these moments was not sure about her feelings, she knew that what she felt for Chica was stronger than only friendship, but with the unpleasant experience she had in her adolescence with Clara, she was determined to repress her feelings towards Chica, and keep flirting with guys until one was the right one. Chica was about to declare her love to Stacy, but it was at that moment that Stacy told Chica that she had gotten a new date. Chica was upset that Stacy didn't follow her advice to stop practically being a "Whore" so she told her that she was fed up, she didn't want to continue being her friend because she was disappointed in her (that and that she was also heartbroken) Stacy was also destroyed.
Days passed and Stacy was on her date with the new boy she began to see, and in a long reflection of ideas she realized that the only person who made her feel that nice was Chica, she knew that Chica was the only one who understood her. She supported her and so on, so she decided to leave everything to get back with her and try to have her on her side. She spoke with her date boy and for her luck he understood. Stacy left her date to run to Fazbear's, where Chica was working at that time.
When Stacy arrived, they were in the middle of the meal and Chica was delivering the dishes with pizza and cake. Chica realized that Stacy had arrive, so she decided to ignore her. Stacy approached to her and told her that she wanted to talk to her, Chica told her not to bother her, Stacy took her by the arm and pulling her told her that they should be serious.

Chica decided to take Stacy to the locker room, to talk quietly.

Chica: "I hope you have a good explanation Stacy ... I'm in the middle of work! Besides, aren't you supposed to be on a date?"
Stacy: "Listen, I know I disappointed you... I did many things that hurt you and I don't expect you to forgive me... but if you will not talk to me anymore, unless I want you to know my true feelings about you"
Chica: "Feelings for me? How about you? You never respect yourself... you mess with every guy that crosses you... Sometimes I worry a lot about you and you ignore when I try to protect you..."
Stacy: "Chica, I'm really sorry... seriously... and I don't expect you to understand it... but I think I'm finally following my heart... the truth is... you don't need to worry anymore for all those boys with whom I flirt, they dont interested me anymore... The truth is that ... I really like you ... "

Chica was really impressed and somewhat confused... she was silent looking at Stacy. Stacy lamented, leaned into Chica's chest, taking her by her arms

Stacy: "I swear I didn't know whether to tell you before or not... but I've been trying to repress this feeling for you... I was afraid to let it out... since... I've never had any luck with girls... but, seriously I hope you understand... how much I love you..."

Chica didn't say anything, just started to bring out the tears.
