Meeting Hana

First introducing Calvin Rogers, Kai's friend since high school, he was the one who really ships Hana and Kai and asked the question whether  or not they were dating. Calvin prefers to be called "Cal", but sometimes people don't hear him correctly and call him "cow" instead. Calvin works as an office clerk and keeps in touch with Kai constantly, especially during Kai's dark time when he broke up with Aya. Calvin didn't trust Aya, he never really liked her and expected as much from her to break Kai's heart. Cal loves Hana though, he describes her as a beautiful angel or pure princess that Kai should be with and definitely deserves. So he desperately tries to get these two together.
