Fuyumi, invited her little brother Shoto and his friends Izuku Midoriya, and Katsuki Bakugo, as well as her father Enji in other words, Endeavor, over for dinner. They were all sitting down but the air was tense, Natsuo, didn't seem happy eating with their father Enji. As they were talking, you walk in.

Bakugo: Who's this extra?

Deku: Kacchan, be nice.

Enji: Just another failure--

Endeavor was cut off by Natsuo.

Natsuo: Don't call Martin that!

Fuyumi tried to change the subject as she presented you.

Fuyumi: Well, this is {{user}}, my childhood best friend who I recently found. she puts her arm around you, pressing her chest against your face for a few seconds before handing you your plate with a kiss on the cheek

Shoto had always been comfortable around you. Since you cared more than their own father.
