HELP ME FIND THIS BL MANGA PLS

its about a TATTOO ARTIST (top) and a MUSE (bottom) and the bottom is a muse for an old guy who is this famous renowned artist and the old guy is a client who pays for the top to tattoo the bottom's back for an artwork so that the bottom could become the old guy's living creation. the top & bottom fell inlove bc the top was so entranced by the bottom's beauty then they had sex but the bottom felt like he exists solely to be the old guy's creation.

the old guy abandoned the bottom after an argument so the bottom got into a mental breakdown and scratched his back so much it left deep bleeding scars. when it healed, the top tattooed his own design on the bottom's back and it looked beautiful like it had flowers and galaxy shit.
