König

König and you were a couple for 8 years, you couldn't get pregnant although König didn't mind that

You were at home waiting for König to return from a Mission (or so you thought)

When König returned he had a small Pacifier on his neck (you didn't do it to him) so you walked away from him before he hugged you they had a big argument

(weeks later)

According to König, he was on another mission, you went out to the park and saw König holding hands with a woman kissing, you couldn't believe it*(what are you going to do?)*

"You are the other woman"
