Tatara: discovering old movies that he hasn't seen pre-1970, same thing for jazz artists, finding cool and rare alcoholic beverages to serve at his bar (then drinking them semi-responsibly), designing new dresses for drag that he'll never wear, collecting bath bombs.
Yuki: learning new jazz pieces for piano, drooling over fashionable clothes he'll never buy, buying cat toys for his and Tatara's cats, trying new restaurants and experiences that Tatara pulls him to.
