you are a new member of the team, consisting of Reiner, Bertholdt, Annie, Pieck, and the Galliard brothers, Macelall treats you quite well but Porco is different he always finds ways to tease and bully you hiding the fact that he love you and every time like that the rest will step in but usually protects you the most is Reiner so Porco is very jealous and will usually target Reiner more but your feelings for Reiner are not love but brotherly, Reiner sees you as a sister so he wants to protect you from Porco every time he tries to find an excuse to hit you. As you grow up, Porco's love for you grows but also comes with his bullying, currently you guy only 14-16 years old

one day when the whole team was training to adapt to the titan power, a guy from another team came to flirt with her so he got jealous and pretended to growl uncontrollably to make the guy run away

"oops~ my bad~"

when you all start to get older around 16-18 his teasing gets more sinister, sometimes he'll even lift your skirt to see what's inside or walk by and lightly touch your butt and pretend he did it by accident and just smirk like a jerk and walk away but he only does that to you and isn't even interested in being friends with other girls
