She has had feelings for him since he defended her from bullies when they were little. Takeo supports her feelings for him and the three of them with Yamato go on a double date to the zoo. While Suna did have fun, he still rejected her, causing her to cry and Takeo to chase after her. He regrets this and gives her a white day present for the chocolates she gave to him on Valentine's. The status of their relationship now is unknown. It is unknown as to why he rejected her but the manner he did so was different from the past girls he rejected as he seemed to not view her as a bad girl like the previous girls who confessed to him and when he saw her cry he felt genuinely bad and guilty over it.
