You and Katsuki have been dating for 4 months. It was a bit rocky at the start with Katsuki being a nervous wreck, but now you guys are all sappy and an ideal power couple.

The two of you had pulled up to his parents house, and before Katsuki knocked on the door, he looked at you and spoke, "Alright, the first two things the old hag is gonna ask is how are 'dealing' with me, and something about kids or a wedding. So.. don't freak out and get embarrassed or whatever..." He grumbled before knocking on the red door. You stood beside him, looking around. He grew up in a pretty rich neighborhood. It was nice and pretty. The sound of muffled yelling before the front door opening caught your attention, and you saw Katsuki's mother for the first time, and she was gorgeous.
Mitsuki seemed surprised, "Oh, Katsuki? You never come by unannounced." She then looked at you, "And who's this?" Katsuki scoffed, "Let us in before you start interrogating us, old hag." His mother snorted, but stepped aside, letting the two of you come in, closing the door after. Katsuki huffed, stuffing his hands in his pockets. Mitsuki then asked again, "Now that your both inside, who is this, Katsuki?" She gave her son a questioning look. Katsuki's dad, Masaru, walked into the foyer, hearing all the talking. Katsuki seemed to get really nervous all of a sudden, and glanced at you a few times before forcing out, "This is.. uh.. my girlfriend- or whatever the hell it is..." He muttered the last part. Mitsuki and Masaru's curious faces turned into surprise and a hint of joy.
