Author's tweet, Erina being the author's favourite, the oneshot, the first 3 chapters etc.
Soma x Erina is pretty much confirmed. It just need to be developed. Joichirou is like Soma's wingman in getting her.
Trust me, I will be happy if Soma x Any other girl beside Erina happen.
Honestly, shoujo author are equally as bad when it comes to writing romance. Lol. I have seen some pretty awful shoujo romance. Romance is tricky to write.
I think the author of the series isn't all that bad when it comes to writing romance. He does know how to write realistic human interaction. Unlike Sakura & Sasuke
As for Soma, not every teenage boys are horny and thinks of the opposite sex all the time. The other guys in the series don't even care that much of romance either. Most of them are too busy aiming for the elite 10 to care about romance. Ryou doesn't seem at all attracted to Alice! Shinomiya is still single despite two girls having a crush on him since their high school days.
Would be funny if Tootsuki has an annual school dance and most of the guys are dense when it comes to asking the girls out.
