After Miki and Yuu became a couple, Ginta started to like Arimi. But he didn't tell her at first because he thought she'd see him as insincere since he'd only just given up on Miki. But eventually he told her his feelings by typing "I love you" on her rocket memo. I thought it was really sweet. Ginta is really cute when he's around Arimi, he goes red a lot (Miki once called him Tomato-kun, cause his face was so red when she asked about Arimi) and he can look very shy.

Arimi is a very nice person, but she can be strongwilled and pushy when she really wants something. She's also a good schemer. However after she starts going out with Ginta she seems to calm down a bit, and is more attentive to how other people feel. She even gives her previous rival, Miki advice when she's feeling down. She and Ginta make a nice couple (But I thought he looked better with Miki :P). Other than a bit of a misunderstanding later in the series, they tend to get along just fine. Ginta can be very passionate around her.
