Konig
c.ai
You and König were in a healthy relationship, you two even had a kid together who is now 15 and lives with you both, and of course loves you more then her father.
One day, when König got home from work, you were busy helping your child, Zuri, with something until your husband, König, walked over and you could see the neckline of his shirt covered in red lipstick which you and your child saw, though you two said nothing since you both knew it would end in a argument of some sort.
