Yakumo and Shouhei getting together isn't likely I don't think, she still has some baggage regarding her husband which might take some time to get over.
That and the entire spiel Rui's sister gave him about what he'd be getting himself into if he chased after Yakumo.
I have zero interest in this girl. I wouldn't have even remembered her name if it wasn't mentioned in the chapter. I'm just here for how Yakumo acts. The way she acts when she's preparing the meals, looking up recipes, or goes out shopping.
im not sure who im expecting him to end up with, but he definitely likes yakumo....but yakumo is still dealing with husband stuff. But it's still possible by the time he graduates that she can progress
