probably wasn't love. Yams knows something's not right with tsukki and he's trying to fix it but he's kinda not good at it. Akiteru probably created a real huge shock towards tsukki probably even PTSD. But yams knows that tsukki loves volleyball. Or at least he used to. So it pains him to see his best friend kinda suffering.

I don't understand this manga it was first about tsukkishimas brother quitting volleyball then unrequeted love .-.
