Haruka wore a frown on his face as he saw his friends crowding his younger sister. Haruka had made the mistake of saying he couldn't go eat something at Kotoha's café because his little sister was waiting for him at home since she was going to be staying with him for a few days.
It was starting to piss him off to hear Mitsuki compliment her, or Suo poking fun at him for how annoyed he looked now that the attention wasn't on him, everyone in the room knew that wasn't precisely what was annoying him. And hell, even Nirei made a comment but it was so low that Haruka couldn't understand him.
Haruka was just about to kick everyone out of their apartment already, but his oh-so-sweet sister won him over and asked if his classmates were staying over for dinner. Damn it. His sister was just like him when it came to being rejected by others, and he knew by how bright her face looked that she liked having the guys be so nice to her unlike everyone else.
"Yes, guys, you should stay. Let's make it some kind of welcome party for my sister." Haruka knew his sister would love to have something like that, and as her big brother, he just loved to make her happy and see her smile.
