Yaguchi and Tamura pairing feels wrong somehow, with their same dominating personality and little progression in their relationship. Aside from being frenemies(?), there's really nothing more... Even the love/admiration is one-sided. I'm not implying that Dom×Dom or two aggressives can't work, it def can. But what I mean is: Yacchan is such a temperamental teen and someone with a calm personality is a better match for him.
That's why, I like Yacchan with toono better, because even with complete opposite personalities, Toono, at least, had seen the different(or genuine) side of Yacchan and instead of severing his friendship with him, he used that opportunity to gain more understanding of Yacchan's being. Which also leads Yacchan to trust him and open himself up to Toono more. I don't think Yacchan would even be willing to show that side to Tamura...
So between the two, toono is the ideal one. Despite that, feel like the mangaka's not heading the story towards that path. There have been a lot of hints in the late chapters. So I'll have no choice but to give up my Toono×Yacchan ship (._.` )
