Yosho is having feelings for Kurokawa, even though he denies it to himself, when he saw her looking at the stuffed plush rabbit, the sight rung his heart, it hurt even more when she walked away, because he could see how much she wanted it, he doesn't know that when he gives the plushy to her, her heart will melt, even though that's not what he's meaning to do, he wants to repay her for how much she has helped him, he knows from the way she walked out that she really wanted to buy the plushy but she was worried more about having the money for Mana's gift.
