SpoilerThe boss in the restaurant the uke of sorenari works is the older brother of one of the new parents in this history yadi (^¬^)/
Oooh thanks! I did consider that the guy and the chef boss looked sameish (although a lot of the time that's merely a manga artist's drawing style), but since one obviously can't cook and the other obviously can, I knew they weren't the same person! I liked Chef boss.
So, Baka Updates says this is related to Sorenari, but I can't remember a point of connection. Anybody?
