Conflicted, pretty much obviously. He likes both Saiga and Yasu, and though he pursued Saiga to some extent in the past, he's mostly accepted that they don't really have that much chemistry. On the other hand, he's found he has a lot of chemistry with Yasu, who currently tops Erland's list of 'ones that got away'. So while Saiga/Yasu is hot, and has a decent amount of potential in various ways, he's more likely to be a direct rival to Saiga than anything.

...man, I don't really know who you play anymore, you need to make a list. Uh. Does Tatsuki like the idea of having an enemy? And how about Hikari, what is she up to?
