Linneus and Atros are pretty much the main characters of teahouse. They might not get as much face time as Rhys and Axis, but they're the main coupling/romance/tragedy whatever you wanna call them of the house and every end of issue special will involve them.
They're a slow burn, and my personal favorite, so I hope you enjoy them over time. Takes a while for them to get under your skin but once they do, I think you'll love them like I love them.
Then again, maybe I'm on crack!!
