Happy Birthday to TC! I figure various people would cover the bases regarding his other fandoms (Dr. Who, MST3K, etc.), so I thought I would chip in with Marimite. :D
The basic idea behind the card is that Sei (the hugger) is awesome, flirty and it is hilarious when she flirts with Yumi (the huggee). Therefore, would Yumi being hugged by Sei on your birthday not make it Sei-licious? I rest my case.
