You make me wanna dance~ (KEL TU 026) is a comic published in 2015 on tumblr (and later on DeviantArt) by Kelly Green.
A couple of Ballroom Dancers dance on a heart-shaped background that indicates their mutual love.
“Happy Friday the 13th/Valentine’s Day Eve, Mansion Fans! (This is really only relevant 'cause it has a heart in the background.)”
“It's an extra special Valentine's Day celebration this year, coming right after a Friday the 13th, so I felt like making something for the occasion! And also to use it as an excuse to draw something of the ballroom dancers, heheh.”
