As he heard those words of Hiro while looking him straight in the eye, different complicated emotions started to take shape within his heart. Yet he couldn't bring himself to speak his heart out.
Experiencing Yuya's unresponsiveness, Hiro felt quite pitiful and sympathetic towards Yuya. If possible, he wanted to help Yuya. But Yuya had already built a wall around him. And forcefully taking that wall down would only worsen the situation.
Thus, he decided to leave Yuya by himself for the time being. However that didn't mean that he was giving up on him. It's just leaving him alone for some time seemed the best possible outcome right now since Hiro wasn't good with words in the first place.
"Then I'll get going for now."
Bidding his farewell, Hiro walked past Yuya without waiting for his response.
