I think that they will in the future. He did say he loves her, right? It's just that she doesn't see him that way yet, but she hasn't rejected him; and he has confessed. That's undeniable. So... As much as she'll be keeping watch on him, and Wataru on her, I'm guessing that this, from now on, will be a battle to be for whoever wins her heart.
I want to see a sequel of this where that's juST what happens, and more plot, less comedy in my preference. Just saying.
And since they meant "amends", that means starting over as friends, which was what he said; restarting everything new for a brand new adventure. Like Warau Kanoko- sama, focused on friendship and society, and Tsubaki wasn't rejected nor accepted, she wasn't aware - then bam! On the sequel, Koi dano ai dano, it focuses on the battle for Kanoko's heart!
I just wish they had really gotten together. At the end it just went back to them being in the will they won't they relationship. Also this series feels disjointed at times like chapters are missing, but when I look at other sites none are missing.
